Solution Set: $y \lt 2$ Refer to the image below for the graph.
Work Step by Step
Add 2 on both sides of the inequality to obtain: $y \lt 0+2 \\y \lt 2$ On a number line, the numbers that are less than $2$are found to the left of $2$. Thus, to graph the solution set on a number line, plot a hole (or hollow dot) at $y=2$ and shade the region to its left. (refer to the attached image in the answer part above)
