Exercise 27 Page 175

Find and compare the slope between each pair of points. What does it mean if any of the slopes are different?

Linear? No, see solution.

Practice makes perfect
One way to determine if points are collinear is to calculate and compare the slope of the line between points in the data set. We can do this by using the Slope Formula. Note that it is enough to check each point with just one other point in the data set.
