Interpret Rate of Change Y-Intercept

Why is this function linear?

• This is a linear function because the y-intercept is (0,8)

• This is a linear function because it has a constant rate of change.

• This is a linear function because it does not have a constant rate of change.

• This is a linear function because the slope is -1
