Example4.11.6

Find the slope of the line in the following graph.

This is a grid with a line, passing the points (3,15) and (6,27). A slope triangle is drawn, starting at (3,15), passing (6,15), and ends at (6,27). The label from (3,15) to (6,15) is "6-3=3"; the label from (6,15) to (6,27) is "27-15=12".

We picked two points on the line, and then drew a slope triangle. Next, we will do:

\begin{equation*} \text{slope}=\frac{12}{3}=4 \end{equation*}

The line's slope is \(4\text{.}\)
