Question

Determine whether the function is linear. If it is,state the rate of change.

Answer 1

7.-

Yes, it is a linear function because all the points are on a line.

rate change = (3 - 1) / 0 - 2)

= 2/-2

= -1

rate of change = -1

Number 8

It is not a function because the last point is out of the line.
