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(s) show nonlinear functions?

• Graph I, only

• Graph II, only

• Graph I and Graph II, only.

• Graph I, Graph II, and Graph III

• Linear

What is the slope for the function that passes through the points (24, 28) and (8, 8). Use your calculator to simplify!

What is the equation for the function that passes through the points (24, 28) and (8, 8)?

• y=5/4 x-2

• 8=5/4(8)-2

• y=-2x+5/4

• 28=5/4(24)+2
