plot points on the boundary line. select the line to switch between solid and dotted. select a region to shade it.
Answer
Explanation:
Step1: Identify the boundary line
The inequality is (x\leq3), and the boundary line is (x = 3).
Step2: Determine the line type
Since the inequality is (\leq) (including equality), the boundary line (x = 3) is solid.
Step3: Determine the shaded region
For (x\leq3), we shade the region to the left of the line (x = 3).
Answer:
Plot the solid line (x = 3) and shade the region to the left of this line.
