Question 136152: I do not understand how to solve this out right. I think i know the answer to the question because the teacher told us it was (4,6). I just don't understand how I would get that.
The equations are
y=2x-2
and
y=x+2

You can put this solution on YOUR website!
y=2x-2
y=x+2 subtract these equations
-----------------------
0=2x-x-2-2
0=x-4
x=4 answer.
y=2*4-2
y=8-2
y=6 answer. (4,6)
---------------------------------
solving graphically we get:
y=2x-2 (red Line)
y=x+2 (green line)
