Section 3.2 Practice Linear Functions

Why is this function linear?

• This is a linear function because it is going up
• This is a linear function because it is a straight line.
• This is a linear function because the line is curved.
• This is a linear function because it keeps going.

Why is this function linear?

• This is a linear function because the y-intercept is (0,2)
• This is a linear function because it forms a curved line.
• This is a linear function because is does not have a constant rate of change.
• This is a linear function because is has a constant rate of change.

Which answer choice is true?

• The table represents a linear function because there is a pattern for the x-coordinates and y-coordinates.
• The table represents a linear function because the ratio of the change in the y value and the change in the x value is constant.
• The table represents a nonlinear function because the ratio of the change in the y value and the change in the x value is not constant.
• The table does not represent a function because there is more than one output for at least one input.
