[tex]m=-\frac{1}{3}[/tex]
1) Considering the slope as the rise/run. Let's enumerate that grid
Enumerating the grid, we can state that A( 2,5), B(5,4), and C(11,2)
2) So now, let's find the slope of BC
[tex]m_{BC}=\frac{2-4}{11-5}=-\frac{2}{6}=-\frac{1}{3}[/tex]
Since those points are colinear, the slope of BC = slope of AB for the slope is a measure of how steep is the line.
