8-25.

Choose a few x-coordinates that can be seen in the graph. Estimate their y-coordinates.
Notice the scaling of the graph.

2, −1

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

Try looking for a pattern.

Notice that at x = 0 the y-coordinate is 2.
Try writing an equation, and then check your answerby substituting points found in (a).
