Question

Determine the ordered pair that satisfies the equation, -5x + 3y = 7.

Answer 1

Answer:

C) (7 , 14)

Step-by-step explanation:

Substitute each ordered pair into the equation

-5x + 3y = 7.

A) (2 , -1)

-5(2) +3(1) = -10 +3 = -7  this does not equal 7  so not true

B) (-5 , 3)

-5(-5) +3(3) = 25 +9 = 34  this does not equal 7 so not true

C) (7 , 14)

-5(7) + 3(14) = -35 + 42 = 7  this equals 7 so true

D) (-2 ,−135)

-5(-2) + 3(-135) =10+405 =415  this does not equal 7 so not true
