Question

1. Which equation represents a linear function?

A. y = x - 4
B. y = x + 4
C. x = (y - 2)2
D. y = x + 7​

Answer 1

A, B, D are equations representing a linear function

Explanation:

All linear functions have an equation like the following: y=mx+b, where m is the slope and b is an offset.

A. y=x-4, m=1 and b=-4

B. y=x+4, m=1 and b=4

D. y=x+7, m=1 and b=7

The third eq dont behave like a linear function since there is quadratic term on one side of the equation, this is not a linear function
