Question

what are the points where they intersect x-2y=-2 and 3x-2y=4

Answer 1

you gotta right the equations as y= ax+b and y_{1}=\[a _{1}x+b_{1}\]
then sove y=y_{1}
for your example:
x-2y=4 and 3x-2y_{1}=4
<> x-4=2y 3x-4=2y_{1}
<> y=x/2 -2 3x/2 -2=y_{1}
solve y=y_{1}

Answer 2

is it 4,4

Answer 3

x-2y=-4 not -2

Answer 4

(3, 2.5) is the point of intersection

Answer 5

and its with the x-2y=-4

Answer 6

then x=0
