solve the systems of equations by graphing

  • algebra -

    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
