    consider any point, say x = 3 ,y=0 does it satisfy the above equation ??

    yes.. because any whole number is more than the - slope

    This is for the first question the shaded area is below where you can find the zeros of the inequality.

    ok, for x-y >-4 consider origin, 0,0 0>-4 this is true, so, 0,0 lies in shade.

    The is the "y" intercept. For the "x" intercept just make y=0 and solve the expression x-y>-4 algebracallly.
