Explanation:
The slope of BC can be calculated
Slope = rise/run
In this case, the rise is the height of the blue triangle and the run is the base of the blue triangle, so
Slope = 2/6 = -2/6
To simplify the slope, we need to divide by 2, so
[tex]\text{Slope}=-\frac{2\div2}{6\div2}=-\frac{1}{3}[/tex]
