A linear function is a function that:

• has a constant rate of change and graphs as a straight line

• has a variable rate of change and graphs as a curve

• has no rate of change and graphs as a point

• has a constant rate of change and graphs as a curve

What is the general form of a linear function?

• y= mx + b

• y = a/x + b

In the linear function y = mx + b, what does 'm' represent?

• slope

• intercept

• variable

• constant

In the linear function y = mx + b, what does 'b' represent?

• y-intercept

• slope

• x-intercept

• origin

What does the common difference in an arithmetic sequence correspond to in a related linear function?

• The y-intercept

• The slope

• The vertex

• The axis of symmetry

Is this an arithmetic sequence? Why or why not?

• Yes, it is an arithmetic sequence because it has a common difference.

• No, it is not an arithmetic sequence because it does not have a common difference.
