What is the slope?

• 1

• 1/2

• 2/1

• -2

Is this function linear or non linear?

• Linear
• Non Linear

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.
