Answer:
A, B, D are equations representing a linear function
Step-by-step 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
