To solve this, you want to put in -8 for the x in the equation, then solve for y. It should = 31.

So checking the first option, A, you have

y = -4(-8) - 1

y = 32 - 1

y = 31

Since this matches the y coordinate of the point, it is the correct answer.

a (y=-4x+1), as the function there is the only one that produces 31 if x=-8.

-8*4=32

32 - 1 =31

a.y=-4x-1

a..y=-4

b.y=-3x-9.

=-27

c.y=x+4

=4

d.y=-2x-1?

=-1

b,y
