Work Step by Step

The solutions of $x \lt -2$ are all real numbers that are less than $-2$. These numbers are graphed on a number line by shading all points to the left of $-2$. To graph this inequality, plot a hollow dot (or a hole) at $x=-2$. (Alternatively, an parentheses may be used instead of a hollow dot.) Then, shade the numbers to the left of $x=-2$. (refer to the attached image in the answer part)
