Visualizing Safety Thresholds

A maintenance technician is creating a visual safety chart for a pressure-release valve based on the compound inequality 5−3x≤−1{}5 - 3x \leq -1 or 8+2x≤5{}8 + 2x \leq 5. According to the step-by-step graphing instructions for this specific example, a bracket is placed at the value −32{}-\frac{3}{2} (the decimal equivalent of -1.5). In which direction (left or right) from this bracket should the technician shade the number line to represent the solution for this part of the inequality?
