Use the table below to determine whether f(x) could represent a linear function. If it could write f(x) in the form f(x) = mx +b.

Answers

Answer:

5x-3

Step-by-step explanation:

This is linear because the numbers are changing at a constant rate (of 5)

We can also see that when x=0 y= -3 which means that in our equation

y=mx+b

-3 =b

I said prior that the rate of change is 5 which means that our slope is 5

which means that our equation looks like
