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

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

ok, for xy >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 xy>4 algebracallly.
