Linear vs Nonlinear Scatterplots

Which graph depicts a nonlinear function?

• Graph A

• Graph B

• Graph C

• Graph D

Describe the association of the scatter plot

• Linear; positive association

• Linear; negative association

• Non-linear

Why is this function nonlinear?

• This is a nonlinear function because it is on the side.

• This is a nonlinear function because it is a straight line.

• This is a nonlinear function because the line is curved.

• This is a nonlinear function because it is open ended

Does the scatter plot show a linear or nonlinear association?

• Linear Association

• Nonlinear Association

Is the relationship LINEAR or NONLINEAR?

• Linear

• Nonlinear

Answer explanation

It forms a straight line, which means it it shows a linear relationship with a constant rate of change.

Match the scatter plot to the equation that could represent the equation of its trend line.

• None of the descriptions match

• The relationship is linear

• The relationship is not linear.

Martin and Daisy are arguing about which graph below represents a non-linear relationship. Martin believes Graph A represents a non-linear relationship, but Daisy thinks it is Graph B. Which of the following statements explain who is correct and why? 

• Graph A, because a trend line cannot be drawn through the data points

• Graph B because a trend line cannot be drawn through the data points

• Graph A

• Graph B

• Graph C

• Graph D

• Function I, only

• Function II, only

• Function I and Function II, only

• Function I, Function II, and Function III

Which graph is linear?

• A
