Linear or Nonlinear Graphs and Equations

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 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)

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.

Why is this function nonlinear?

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

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

• The function is nonlinear because the y-intecept is (0,1)

• This function is nonlinear because there is a coefficient of 4.

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.

Is this function linear or nonlinear?
