2X-Y=1. (0,-1), (1,1)

8X-4Y=8. (0,-2), (1,0)

The solution of the two equations is the point where their graphs intersect.

The graph using the above points showed that the lines are parallel and

do not intersect. Therefore. there is no solution. The two lines have equal

slopes which further proves that they are parallel. Slope1=-A/B=-2/-1=2, Slope2=-8/-4=2. If you solved the two equations mathematically using the

elimination method.the results will

be 0=4 which is not a true statement

and further proves that there is no

solution.
