5+-4=-1 and that is greater than equal to -7. Always.
The graph is the line, and the point either falls on one side or the other. The side where the inequality works can be determined by using (0, 0). That satisfies the equation above, so everything to the upper right of the equation works. Because the point (-2, 5) is in this region, it always works.

.

Substitute the given coordinates into the inequality and CHECK if it is valid.

So simple assignment you can (should and MUST) do on your own
without asking for the help from outside.
