Example 1

Check each ordered pair to see if it is a solution to 3x + 2y ≥ 6.

(0, 3)

(4, 2)

(-1, 3)

Plug, plug, plug; chug, chug, chug. In, out, and get it done.

3(0) + 2(3) ≥ 6?

0 + 6 ≥ 6

The inequality allows just a little bit of equality, so it squeaks on through. This is a solution to the equation.

3(4) + 2(2) ≥ 6?

12 + 4 ≥ 6

16 ≥ 6

Yes, this is true. This ordered pair is a solution.

3(-1) + 2(3) ≥ 6

-3 + 6 ≥ 6

3 ≥ 6
