Question

Select all the ordered pairs that are a solution to the equation 3x + 2y = 2?

(2,-2)
(0, 1)
(3,0)
(5,1)

Answer 1

3x + 2y = 2

Substitute each ordered pair and see if it works.

(2,-2)

3(2) + 2(-2) = 6 - 4 = 2

so yes, (2,-2) is a solution.

(0,1)

3(0) + 2(1) = 0 + 2 = 2

so yes, (0,1) is a solution.

(3,0)

3(3) + 2(0) = 9 + 0 = 9

NO, (3,0) is not a solution.

(5,1)

3(5) + 2(1) = 15 + 2 = 17

NO, (5,1) is not a solution.
