Solution Set: $x \le 6$ Refer to the image below for the graph.
Work Step by Step
Subtract 4 on both sides of the inequality to obtain: $x \le 10-4 \\x \le 6$ On a number line, the numbers that are less than or equal to $6$are from $6$ to the left.. Thus, to graph the solution set on a number line, plot a solid dot at $x=6$ and shade the region to its left. (refer to the attached image in the answer part above)
