We have [tex]P_1(x_1,y_1)\to P_1(8,15)[/tex] and [tex]P_2(x_2,y_2)\to P_2(5,9)[/tex].

The slope is

[tex]m=\dfrac{\Delta{y}}{\Delta{x}}=\dfrac{y_2-y_1}{x_2-x_1}=\dfrac{9-15}{5-8}=\dfrac{-6}{-3}=\boxed{2}[/tex]

Hope this helps.

Answer:

The slope is 2.

Step-by-step explanation:

Slope, usually represented by m, is m = rise / run.

If we go from the point (5, 9) to the point (8, 15), x increases by 3 (this is the run) and y increases by 6 (this is the rise).  

Thus, the slope is m = rise / run = 6/3, or 2.

The slope is 2.
