Answer:
Step-by-step explanation:
The change in y is the difference in y-coordinates between the lower right point and the upper left point. Similarly, the change in x is the difference in the x-coordinates of those points.
[tex]\text{Slope}=\dfrac{\text{change in y}}{\text{change in x}}=\dfrac{\boxed{3}-6}{2-\boxed{1}}\\\\=\dfrac{\boxed{-3}}{\boxed{1}}\\\\\\=\boxed{-3}[/tex]
