8x-6y=-18 = y=4x/3 +3 and 8x+7y=9 is 8x/7+9/7
Answer:
C. -24
Step-by-step explanation:
(x+6)= -18
Subtract 6 from each side
x+6-6 = -18-6
x = -24
Answer:
Step-by-step explanation:
I would say B
Direct variation is of the form y=kx. We are given the point (8, -4) so we can solve for k, the constant of variation...
-4=8k, divide both sides by 8
-4/8=k
k=-0.5, so our equation is:
y=-0.5x,
