Question

Which of the following functions is NOT a linear function?

A y = 5
B
y == 5x
C y = 5(x - 2)
D y == 5x – 2 + x?

Answer 1

A. y = 5, is the correct answer.

B, C, D are all able to form into the y = mx + b equation, so it's not correct. A is not able to form that equation, therefore, A is correct. Hope that helps :)
