match the graph to its equation

1 .

y = (¼) x

2 .

y = 4 x

3 .

y = 2 x

4 .

y = (½) x

y=1/4x is:

stay on the 0-y. Move 1 up and 4 to the x side.

y=4x is:

stay on the 0-y. Move 0 up and 4 to the x side

y=2x is:

stay on the 0-y. Move 0 up and 2 to the x side.

y=1/2x

stay on the 0-y. Move 1 up and 2 to the x side.

answer:

125 yards

explanation:

75+50=125. that is my answer

x² + 3x + 7 = 0       [ax² + bx + c]

a = 1

b = 3

c = 7
