make one y1, and the other y2
set y1 = y2
2x-4 = -x +5
then collect like terms by bringing all x's to one side and all "numbered" valued to the other (change the signs)
2x + x = 5 +4
3x = 9.
x=9/3 x = 3
depending on how far you need to go with this question.....sub x value back into one of the origial equations (either y1 or y2...i'll do both, you will get the same answer for the value of "y")
y1 = 2 (3) -4 y2 = -(3) + 5
y1 = 6-4 y2 = -3 + 5
y1=2 y2 = 2
therefore the points on the graph would be (x,y) = (3,2)
