Question

Help fan and medal!! What is the slope of the line passing through the points (0, 4) and (–8, –1)?

Answer 1

just do rise over run

Answer 2

see thats what i dont get.

Answer 3

\(\bf \begin{array}{lllll}
&x_1&y_1&x_2&y_2\\
&({\color{red}{ 0}}\quad ,&{\color{blue}{ 4}})\quad &({\color{red}{ -8}}\quad ,&{\color{blue}{ -1}})
\end{array}
\\\quad \\

slope = {\color{green}{ m}}= \cfrac{rise}{run} \implies \cfrac{{\color{blue}{ y_2}}-{\color{blue}{ y_1}}}{{\color{red}{ x_2}}-{\color{red}{ x_1}}}\)
