Which set of coordinates represents a linear function? a. (0,0), (1,4), (2,16) b. (-1,1), (0,-2), (1,1) c. (-2,-2), (4,2), (8,6) d. (-1,-3), (2,1), (5,5)

A is an exponential function. It is not linear because the growth rate is not the same.

B is a quadratic function. It is not linear because again, the growth rate varies.

C is not a linear function. This is because the y changes constantly but the x changes by 6, then 4.

D is a linear function because the growth rate is the same.
