Points X, Y, and Z are colinear.xWhat is the slope of YZ in simplest form?[?]

The slope of a segment can be calculated by dividing the rise (change in the vertical direction) and the run (change in the horizontal direction).
Looking at the segment YZ, the horizontal distance is 3 units and the vertical distance is 6 units.
Therefore the slope is:
[tex]\begin{gathered} m=\frac{\text{rise}}{\text{run}} \\ m=\frac{6}{3} \\ m=2 \end{gathered}[/tex]The slope of YZ is equal to 2.
