Answer

Refer to the image below for the graph.

Work Step by Step

To graph the given inequality, do the following: (1) Graph the boundary line $y=4$. (refer to the attached image below for the graph) (2) Choose a test point that is not on the boundary line. Substitute the x and y values of the test point into the inequality. Let $(2,0)$ be the test point. $0 \le 4$ This statement is true therefore the solution to the inequality is the half-plane that contains the test point. Shade that region to complete the graph. (refer to the attached image in the answer part for the graph)
