8-25.

Use the graph below to answer the questions below.

Create a table of values for the line on the graph such as the one started below. Include at least

entries. Choose a few

-coordinates that can be seen in the graph. Estimate their-coordinates.

Notice the scaling of the graph.

What is the slope of the line?

Notice that since the line slopes downward, its slope will have a negative value.

Write an equation (rule) for the line.

Try looking for a pattern.

Notice that at

the-coordinate is.

Try writing an equation, and then check your answer by substituting points found in (a).
