Question 192377: 8x - 4y = 12 and -4x + 2y= -6 Solve the system, graph the system, and interpret the graph. Found 2 solutions by Mathtut, edjones:Answer by Mathtut(3670) (Show Source):
You can put this solution on YOUR website! 8x - 4y = 12 ---->-4y=-8x+12--->y=2x-3
-4x + 2y= -6----->2y=4x-6------>y=2x-3
:
since these are the same lines there are infinite solutions.

-4x + 2y= -6
.
Change equations to slope intercept form to graph (solve for y):
8x - 4y = 12
-4y=12-8x
y=2x-3 divide each side by -4
.
-4x + 2y= -6
2y=4x-6
y=2x-3
.
the equations are the same.
