Write the equation of the line that passes through the points (9, 3) and (-7, -7).
Put your answer in fully reduced point-slope form, unless it is a vertical or horizontal
a
line.
Answer:
y-3=5/8(x-9)
Step-by-step explanation:
First, we can find the slope using the slope formula : -7-3/-7-9 = -10/-16 = 5/8
Now we can just plug in a point into point slope form
y-3=5/8(x-9)

33-37 odd *equations only* Help pleaseeee I didn’t even know about this until 20 mins ago
[33] x = 140° & y = 118°
The lines are parallel, sso we can tell that y will equal 118° degrees because of corresponding angles. Then for x, we can add the non-adjacent angles together, 118° + 22° = 140°
[35] x = 26° & y = 64°
x will be 180° - 90° - 64° = 26° because a triangle's angles are equal to 180° and the box represents a 90° angle. y is equal to 64° because the lines are parallel, and if we "flip" one of the triangles around we can see that y and 64° are corresponding angles. (to check, we add 26° + 64° + 90°, and it does equal 180°!)

PARALLEL PERPENDICULAR OR NEITHER OR SAME LINE
Answer:
Parallel
Step-by-step explanation:
Solving the equations, we come out to:
A. y = 1/4x + 1
B. y = 1/4x - 1
This would make the lines Parallel because the slope is the same
What is the solution to the system of equations?
y = 2x + 3
y = -x +8
Answer:
x= 5/3
Step-by-step explanation:
You would set the equations equal to each other, so 2x + 3 = -x + 8. Then, you would add the x to the 2x making it 3x. That makes your equation 3x + 3 = 8. Then you subtract the 3 making the equation 3x = 5 and then you would divide the 3 making your answer 5/3.

Martha, Brett, and Mike are competing in a cooking competition. They all used different amounts of oil from a can containing 8 gallons of oil.
Martha used 17% of the total oil in the can.
Brett used 0.18 of the total oil in the can.
Mike used 0.7 gallon of the total oil in the can.
Who used the greatest amount of oil from the can? Show your work and explain your answer in words. (10 points)
Answer:
Mike
Step-by-step explanation:
17% = .17
.7 = .70
All that's left is to compare the amounts of oi for each person and decide who has the most, which would be Mike. Hope this helps! (Rate brainliest!)
Answer:
Brett used the most
Step-by-step explanation:
Martha used = 17%
Brett used = 0.18 = 18/100 = 18%
Mike used = 0.7 × 100/8 = 8.75% (he only used 0.7 of ONE of the gallons in the can, not of the total oil in the can)
Therefore, Brett used the greatest amount of oil.
Find the slope of the line x=+6
Step-by-step explanation:
x = 6
is a straight vertical line (parallel to the y-axis, going through x=6 on the x-axis).
it's slope is therefore undefined (infinite). every possible y value (from -infinity to +infinity) is associated with this one x value (6).

A pineapple is 7 times as heavy as an orange. The pineapple also weighs 870 grams more than the orange.
What is the total weight in grams for the pineapple and orange?
Answer:
1015 g and 145 gStep-by-step explanation:
Let pineapple = x, orange = y
A pineapple is 7 times as heavy as an orange:
x = 7yThe pineapple also weighs 870 grams more than the orange:
x = y + 870Compare the two equations above:
7y = y + 8706y = 870y = 870/6y = 145Find the value of x:
x = y + 870 = 145 + 870 = 1015[tex]\huge \bf༆ Answer ༄[/tex]

[tex]y = \dfrac 32 x - \dfrac 38\\\\\\\text{The above equation is in a form of y =mx +b, where m is the slope.}\\\\\\\text{Hence the slope is}~ \dfrac32[/tex]
Answer:
Slope: 3/2
Step-by-step explanation:
Our equation: y = mx + b
Given equation: y = -3x/2 - 3/8
=> Now, let's compare:
=> y = mx + b = y = -3x/2 - 3/8
We can tell that slope = m, which is 3/2.
Hoped this helped.
what's the slope?
what is the y-intercept?
proportional or not proportional?
Answer:
Slope: 16
y-intercept: (0, 0)
Yes it is proportional
Step-by-step explanation:
What's the slope
To find the slope we can do rise over run.
192 - 96 96
----------------- = ----------- = 16
12 - 6 6
So the slope is 16
What is the y-intercept?
For the y intercept we can just look where the line crosses the y-line so (0, 0)
We can check that by inputing some numbers:
y = mx + b -------> 96 = 6 · 16 + b
96 = 96 + b
- 96 - 96
0 = b
in this equation b represents the y-intercept
Is it proportional?And the definition of a proportional slope is if the equation is y = mx, which in this case it is true, as the equation is y = 16x. (m is the slope which we've already found above)
So evidently the slope is proportional.

There is a line that includes the point (-20, -7) and has a slope of 1. What is its equation in
slope-intercept form?
Write your answer using integers, proper fractions, and improper fractions in simplest form.
Answer:
y=1x+13
Step-by-step explanation:
we can plug in the two points into the slope-intercept formula
-7=-20(1)+b
solve for the right side
-7=-20+b
add 20 to both sides
13=b
plug the y intercept into the equation
y=1x+13
How would you solve for x and y and what are x and y? Not sure what to do.
Answer:
x = 26 2/3
y = 50
Step-by-step explanation:
you could set '2y-3x' equal to '-3x+y+50' because they are vertical angles
2y - 3x = -3x + y + 50
add 3x to each side to get:
2y = y + 50
y = 50
also, we know that (1/2y + 25) + (2y - 3x) = 180 because they form a straight line
3/2y + 25 - 3x = 180
subtract 25 from each side to get:
3/2y - 3x = 155
substitute 50 for 'y' to get:
3/2(50) - 3x = 155
75 - 3x = 155
-3x = 80
x = 26 2/3
An automatic doughnut machine can produce 1500 doughnuts in 9 hours.
How long would it take the machine to make 300 doughnuts?
Answer:
1 hr, 48 minutes
Step-by-step explanation:
you can create a proportion:
doughnuts/hours = doughnut/hours (h)
1500/9 = 300/h
cross-multiply to get:
1500h = 2700
h = 27/15
h = 1 12/15, which is 1 hr, 48 minutes because 12/15 = 48/60

The sum of two numbers is 52. The greater number is 4 more than the smaller number. Which equation can be used to solve for the smaller number ?
×-(×+4)=52
×+(×+4)=52
×(×+4)=52
×(×-4)=52
Answer:Let's assume x be the smaller number.
Given that, The greater number is 4 more than the smaller number.
So, greater number= x+4.
It's also given that, The sum of two numbers is 52. Which means sum of x and x+4 must be equa to 52. Hence,
x + (x + 4) = 52

Answer:
Choice D
Step-by-step explanation:
Factorise: 4x²-9y²
We can obtain the factorization by this identity:
a² - b² = (a+b)(a-b)Rewrite the given expression as:
(2x)² - (3y)²Let (2x)² be a and (3y)² be b according to the identity.
So applying the identity:
(2x+3y)(2x-3y)(2x-3y)(2x+3y)Choice D is accurate.
