Question

Which ordered pair is NOT a solution of the inequality 3x − 2y ≥12?
(-1, -7)
(-3, -10.5)
(0, -6)
(2, -3)

Answer 1

Hello,
To figure this out, just plug in your x and y values. For instance, if I wanted to find out if (-1, -7) was a solution of 3x − 2y ≥12, I'd use -1 for my x value and -7 for my y value. It would look like this: 3(-1) − 2y(-7) ≥12. After you perform all the operations on it, see if your answer is greater than or equal to 12. In this case, I get 11 ≥12. Since that isn't true, we can throw out (-1, -7) as a possible solution. Hope this helps :)
