solomonzelman · Answer

graph them and at the point where they intersect is the answer.
to graph them, put them in y=mx+b from and plug in x values.

try the points, substitute x and y to see which one is true

i think its B, is that right?

ivettef365 · Answer

lets try B  (3,-1)  (x,y)
-2x=2y-4   =     -2(3) = 2(-1) -4
                          -6    = -2 - 4
                           -6    =   -6    ok, works
2x-y=-5     =     2(3) -(-1) = -5
                           6  + 1 = -5
                               7 = -5    not good

need to keep trying
