ANSWER

D. 6

EXPLANATION

We want to find the y-coordinate of the point of intersection of

-3x+2y=6

and

4x-y=2

Solve for y in equation (2) to get:

y=4x-2

Put y=4x-2 into the first equation:

-3x+2(4x-2)=6

-3x+8x-4=6

-3x+8x-4=6

Divide both sides by 5 to get

x=2

This implies that:

y=4(2)-2

y=8-2=6

2

step-by-step explanation:

y/x of point b= y/x of point a
