Section 7.1 Slope of a Line
Definition 7.1.
The slope of a line measures how slanted it is. If we know two points
Example 7.2.
Suppose we want to compute the slope of a line between the points
Let's check that if we subtract the other way around, we indeed get the same answer:
Checkpoint 7.3.
Compute the slope of the line between the points


Example 7.6.
Let's compute the slope of the line below

Let's pick the point

Checkpoint 7.7.
Compute the slope of the line below:
