In Example 5, if the first y-coordinate is changed to −2, what changes result in the example?

Data from Example 5

Find the slope of the line through (−1, 2) and (3, −1). In Fig. 5.6, we draw the line through these two points. By taking (x₂ , y₂) as (3, −1) and (x₁ , y₁) as (−1, 2), the slope is

The line falls 3 units for each 4 units in going from left to right.
