Question 56515
2x-y=4 [Re-write in the slope-intercept formate by solving for y]
-y=-2x+4
y=2x-4 [Graph]
.
2x-y=6
-y=-2x+6 [Re-write in the slope-intercept formate by solving for y]
y=2x-6 [Graph]
.
The lines are paralled because they have the same slope.  Therefor, the lines do not have a common point of intersection]

.
