The given inequality is $ x > -3$

Consider the equation $x=-3$

It is represented by the dotted line as shown,

Step 2:

The line divides the XY plane into two half planes I and II consider a point 90,0) in the half plane II

We see that $ 0 > -3$ is true.

Step 3:

Therefore the half plane I is not the solution region.

The solution region of the given inequality in the half plane II excluding the line.

It is represented by the shaded region.
