Answer :
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
