Straight Lines Graph the straight lines in Exercises 1–3.
Then find the change in y for a one-unit change in x, find the point at which the line crosses the y-axis, and calculate the value of y when x 52.5.
1. $$y x\ 5\ 1\ 2.0\ 0.5$$
2. $$y x\ 5\ 1\ 40\ 36.2$$
3. $$y x\ 5\ 25\ 6$$
Scatterplots For the scatterplots in Exercises 5 describe the pattern that you see. How strong is the pattern? Do you see any outliers or clusters?
