Representing Linear Inequalities

Write the system of inequalities Carlos works at a movie theater selling tickets. The theater has 300 seats and charges $7.50 for adults and $5.50 for children. The theater expects to make at least $2000 for each showing. Which region represents less than 300 seats sold?

• Red

• Blue

• Purple (red and blue overlap)

• Non Shaded

Rewrite this inequality in "y=" form to graph.  3x - 6y > 12

• y > ¹/₂x - 2

• y < -¹/₂x + 2

• y < ¹/₂x - 2

• y > -3x - 2

Graph the solution set for the system of inequalities: 1) 2x - y > 3 2) x + 3y ≤ 5 3) 4x + 2y < 8

• The solution set is the shaded region that overlaps only one of the regions.

• The solution set is the shaded region that overlaps only two of the regions.

• The solution set is the shaded region that overlaps all three regions.

• The solution set is the shaded region that does not overlap any of the regions.
