Consider the graph and equation, y = 3x, that represent Alonso’s walking speed. What relationship is represented by this equation and graph? What would the points (3, 9) and (5, 15) represent? Explain.

Points (−3, 5) and (3, 5) on the coordinate grid below show the positions of two players on a tennis court:

A coordinate plane is shown. There is a point at 3, 5 labeled Player 2. There is a point at negative 3, 5 labeled Player 1.

Which statement best describes the relationship between the positions of the two players? (4 points)

A)
Player 2's position is Player 1's position reflected across the y-axis; only the signs of the y-coordinates of Player 1 and Player 2 are different.
B)
Player 2's position is Player 1's position reflected across the x-axis; only the signs of the x-coordinates of Player 1 and Player 2 are different.
C)
Player 2's position is Player 1's position reflected across the x-axis; only the signs of the y-coordinates of Player 1 and Player 2 are different.
D)
Player 2's position is Player 1's position reflected across the y-axis; only the signs of the x-coordinates of Player 1 and Player 2 are different.
