(Pressing a third time allows you to choose the icon, which resembles a shaded region below a line.)
4. Press to view the graph of the solution set.
All points in the shaded region are in the solution set of y > 2x - 7.
Note that the solution set does not include points on the line y = 2x - 7. The graph of the solution set of the inequality y ≥ 2x - 7 does include points on the boundary line y = 2x - 7.
Lab Practice
Graph the solution set of each inequality.
a. y < 3x + 5; Is the point (1, 1) a solution of the inequality?
b. y ≥ 2x - 5; Is the point (7, 2) a solution of the inequality? c. y < -2x + 3; Is the point (0, 0) a solution of the inequality?
