Which ordered pairs are in the solution set of the linear inequality below?

y>rac{2}{3}x-3

• (6,-4)

• (3,9)

• (3,-1)

• (-3,-3)

• (-9,0)

Which ordered pairs are in the solution set of the inequality below?

• (4,2)

• (-3,-21)

• (2,7)

• (8,4)

• (0,-1)

Recall: an ordered pair solution to a linear inequality lives in the shaded area.

Give one possible ordered pair solution:

Answer explanation

There are many correct answers. Here are just a few possible answers:

Would an ordered pair on a dashed line be a solution?

• Yes

• No

Answer explanation

The dashed line means that we cannot include points on that line as solutions. They do not give a true statement when plugged into the inequality!

Check the boxes of solutions to the linear inequality: y>2x+1

Answer explanation

(5, -2) & (7, 5) are not in the shaded area

• Yes

• No

Answer explanation

(1, 3) is on the dashed line & cannot be included as a solution

Check the boxes of solutions to the linear inequality: 5x-3y≥1

Answer explanation

(-1, -1) is not in the shaded area.
