Question

Does the point (-9, -31) make the equation -3x - 2y = 35 true? Explain

Answer 1

(-9 , -31)

x= -9

y= -31

-3x - 2y = 35 Insert values

-3(-9) - 2(-31) = 35 Remove brackets

27 + 62 = 35 Add left hand side

89 ≠ 35

Therefore the point (-9 , -31) does not make the equation -3x - 2y = 35 true
