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
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).
