To solve the inequality 5x<25, we first need to graph each side of the inequality in our calculators. y>5x y<25 Then we will find any critical points of the inequality by finding the points of intersection between these two graphs. x=5 Since x=5 is a critical value of the inequality, we need to pick two test points - one to the left of x=5 and one to the right of x=5. The test point(s) that gives a "true" statement when we plug in to the inequality is the correct side to shade on.
