Focus Question

How are equations and graphs related?

A ​ (a)   , x and y, is an equation that can be written in the form ​ (b)   where m and b are ​ (c)   . The graph of a linear equation is a line. Likewise, a ​ (d)   is a function whose graph is a ​ (e)   .

• linear equation in two variables
• y = mx + b
• linear function
• nonvertical line
• constants
• nonlinear function
• m and b

A ​ (a)   has a ​ (b)   and can be represented by a ​ (c)   . A ​ (d)   does NOT have a constant rate of change. So, its graph is ​ (e)   .

• linear function
• constant rate of change
• linear equation in two variables
• nonlinear function
• NOT a line
• y = mx + b
• m and b
• graph

Match the following.

• linear

• Graph a

• Graph b shows a constant rate of change.

• Reason Explained:

• nonlinear

• Graph b

Does the graph or table represent a linear or nonlinear function? Select all that apply. (See photo)

• Linear - graph 1 is linear because it shows a constant rate of change.

• Linear - graph 2 is linear because

• Nonlinear - graph 1 is nonlinear

• Nonlinear - graph 2 is nonlinear because it is not a straight line.

Which of the following equations represent linear functions? Explain.
