Question

Which ordered pairs make the equation true?

4x−3y=−10

Select each correct answer.

(3, −1)
(−4, −2)
(1, 4)
(−1, 2)

Answer 1

(- 4, - 2 ) and (- 1, 2 )

Explanation:

to determine which ordered pairs make the equation true

substitute the x and y coordinates of each point into the left side of the equation and if equal to the right side then it is a solution.

(3, - 1 )

4(3) - 3(- 1) = 12 + 3 = 15 ≠ - 10 ← not true

(- 4, - 2 )

4(- 4) - 3(- 2) = - 16 + 6 = - 10 ← true

(1, 4 )

4(1) - 3(4) = 4 - 12 = - 8 ≠ - 10 ← not true

(- 1, 2 )

4(- 1) - 3(2) = - 4 - 6 = - 10 ← true
