1-20.

Jill needs to cut a piece off of a table, graph, and equation) for the function with

*-values that are the length of the piece Jill cuts off and*

*-values that are the length of the piece that is left over. Which representation best portrays the situation? Why? Explain. Homework Help ✎*

Make a table.

What input and output represent the length of the lumber before she cuts it?

Draw a graph. What is the slope?

What is the -intercept? What is the equation?
