Plot the three data points … in a plane

Plot the three data points $(- 1, 2), (0, 6), (1, 4)$ in a plane. Draw the straight line $x + y t$ with the same $x$ and $y$ as in Problem 38. Locate the three errors up or down from the data points and compare with Problem 38.

This exercise builds on another exercise in its source book, which isn't shown here.
