how do u solve an equation using the the graphing method...for example
x-y=2 and -2x=2y=2

just graph then. Two points each and lines
to make it easy, find intercepts, points where x = 0 or y = 0

for the first one it is (0,-2) and (2,0)
for the second one it is (0, oh dear you have a typo probably mean -2x+2y = 2

When you get that straightened out, look for the point where the two lines hit. In fact in this case they will never hit because they have the same slope, 1 if I guessed right about your typo

For each equation, pick values for x and solve for y. Pick at least three pair of x,y values and then plot these points. Draw a line connecting these points.

Do this for each equation. The point where these line graphs intersect is the solution.
