Question

The graph of 9x − 6y = 12 is shown on the grid. Which ordered pair is in the solution set of 9x − 6y ≤ 12?

A) (0, 3)
B) (3, 0)
C) (5, 4)
D) (−2, −6)
???????????????

Answer 1

A is correct. There’s two ways to do this.

1) Process of elimination. Plug x and y in for every equation and see if it is true.
9(0) - 6(3) < 12
-18 < 12 (true)

2) Look at the graph. I assume on your paper/computer you can see a graph. Try to find one of these plots on the graph. (0, 3) should be there.
