Explanation
when you know 2 poitns of a line, you can find the slope by appling
[tex]\begin{gathered} \text{slope}=\frac{change\text{ in y }}{\text{change in x}}=\frac{y_2-y_1}{x_2-x_1} \\ \text{where} \\ P1(x_1,y_1) \\ P2(x_2,y_2) \end{gathered}[/tex]then
let
P1= denver=(0,5280)
P2=loveland=(-70,11990)
replace
[tex]\begin{gathered} \text{slope}=\frac{11990-5280}{-70-0} \\ \text{slope}=\frac{6710}{-70} \\ \text{slope}=-95.85 \end{gathered}[/tex]I hope this helps you
