Does (2, - 1) make this a true statement? Why or why not?

3x + 2y = 4

Answer: Yes

Step-by-step explanation:

So a coordinate pair is always set up (x, y) so you plug the x term in the coordinate pair into the x in the equation and the y term in for the y. 3*2 + 2*-1. Multiply them together and you end up with 4.
