You probably meant:
y = -4x - 9
sub each given point into the function to see if it works
I will do c) for you
Does (-6,15) satisfy y = -4x - 9 ? Let's see ...
15 = -4(-6) - 9
15 = 24-9 , well, what do you know, I lucked out.
Try the others, there may be more
which ordered pair is not a solution of -4x-9
a.-9,27
b.3,-21
c.-6,15
d.5,-28
