Is the function represented by the table linear or nonlinear?

• Linear

• Nonlinear

Is the function represented by the equation linear or nonlinear?

• linear

• nonlinear

Is the function represented by the table linear or nonlinear?

• linear

• nonlinear

Is the function represented by the graph linear or nonlinear

• linear

• nonlinear

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.

Which graph is linear?

• A

• B

• C

• D

Why is this function linear?

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

• This is a linear function because it creates a curved line.

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

• This is a linear function because it's y-intercept is (0,2)
