Question

Which function is a linear function

Answer 1

B is your answer

Explanation:

Answer 2

B

Explanation:

First a linear function has no variables to a power other than 1

That means we can eliminate answers A ,C D and E

Looking at B

y + 7 = 5x

Subtract 7 from each side

y+7-7 = 5x -7

y = 5x-7

This is in the form of a line (y=mx+b)

This is linear
