Solutions to Inequalities on a Graph

The ordered pair (x, y) must be in the shaded or true area
The ordered pair can be on the line if the line is SOLID
The ordered pair is NOT a solution if it is on the line and the line is dashed (< or >)

Multiple Choice

Is the point (3, 1) a solution for the following inequality? Choose the best answer that has the best explanation.

Yes because it is located in the shaded region.

No because it is located on the line and the line is dotted.

Yes because it is located on the line.

No because it is in the shaded region.

Multiple Choice

Which point below is NOT part of the solution set?

(0, 0)

(-5, 0)

(3, 5)

(0, -2)

Multiple Choice

Which ordered pair is a solution of the inequality?

y ≥ 4x – 5

(3, 4)

(3, 0)

(2, 1)

(1, 1)

Multiple Choice

Determine whether point A is a solution to the linear inequality that is shown.

Yes

Sometimes

Graphing linear inequalities

Check if the line is solid or dashed
Check the b value and slope of the graph.
Test (0,0) to see if the area is true

Multiple Choice

Nick had $26.50 to spend at the fair. Admission to the fair was $8.50 and rides cost $1.50 per ticket. Which inequality and solution represents how many ride tickets Nick can purchase?

8.50 + 1.50x < 26.50; Nick can purchase more than 12 tickets

8.50 + 1.50x > 26.50; Nick can purchase more than 12 tickets

8.50 + 1.50x ≤ 26.50; Nick can purchase no more than 12 tickets

8.50 + 1.50x ≥ 26.50; Nick can purchase no more than 12 tickets

Multiple Choice
