Use a graph to show the region defined by these 2 inequalities

  1. Feb 5, 2012 #1
    1. The problem statement, all variables and given/known data
    Use a sketch graph to show the region defined by y<2 and y>x


    3. The attempt at a solution

    y<2 is easy as its anything below y=2...

    but im totally stuck on y>x.. How can I know what y is if i dont know what x is??

    thanks for any help

    Hint -- plot the line y=x...

    oh man of course it is.... because its a linear eqaution right?

    so if it were y>x-2

    you would plot y=x-2

    and the same as y>x

    you would ploy y=x

    so thats diagonal 1234567 etc...

    thanks
