Linear Functions

Determine the slope and y-intercept from the following equation:   y = 3/2x + 3

• slope: 5   y-intercept:  (0,3) 
• slope: 3/2   y-intercept:  (0,3) 
• slope:  4  y-intercept:  (0,3/2)
• slope: 1/5   y-intercept:  (0,5) 

Find the slope from the table.

• -4
• 1
• 4
• -2

Find the slope

• -5/3
• -3/5
• 5/3

If my function rule is 2x + 1, what is the OUTPUT if the input is 2?

• 5

• 4

• 22

• 23

Level 3 Which equation matches the table?

• y = x + 5

• y = 5x

• y = x - 5

• x = y - 5

Is this function linear or nonlinear?

• Linear

• Nonlinear

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)

Is the equation linear or nonlinear?

• Linear
• Nonlinear
