Kindly check below.
1) Usually, whenever we need to graph an inequality, we need to treat it as if it was an equation.
2) So if we consider that x=-2 is a vertical line that passes through point -2, we can start with that.
3) Since the sign is < then we need to plot a dashed line delimiting the region to be shaded, given that -2 is not included. And finally, as it is lesser than -2 we can paint the region to the left of -2, where the numbers lesser than -2 are located.
4) So, our graph is:
