Solving Systems by Graphing Inequalities

Match the system to the graph (solution set is on the left)

• y ≤ 3x   and  y ≤ -2x + 4
• y > 3x   and  y > -2x + 4
• y < 3x   and  y > -2x + 4
• y > 3x   and  y < -2x + 4

Match the system to the graph.

• y > -1/5x - 1/2   and  y ≥ -2x - 4
• y > -1/5x - 1/2  and  y ≤ -2x - 4
• y ≥ -1/5x - 1/2   and  y ≤ -2x - 4
• y < -1/5x - 1/2   and  y ≥ -2x - 4

Match the system to the graph. 

• y ≥ -x - 1 and y < x + 4
• y < -x - 1 and y ≥ x + 4
• y > -x - 1 and y ≥ x + 4
• y > -x - 1 and y ≥ x + 4

Match the system to the graph (solution set is the purple area)

• y > -4/5x - 1 and y ≤ 2/3x + 3
• y ≥ -4/5x - 1 and y ≤ 2/3x + 3
• y < -4/5x - 1 and y < 2/3x + 3
