Question

Which of the following would be on the

graph of y = 2.5x -7?

(0,0) (2, -2)

(3,4) (-2, 2)

Answer 1

y = 2.5x - 7

For each coordinate, substitute the x-coordinate for x and the y-coordinate for y and see if the two sides of the equation are equal.

For example, (0,0)

0 ? 2.5*0 - 7

0 ? -7 no doesn't match so wouldn't be on the graph
