Question

Determine the slope of the line that contains the points G(8,1) & H(8,-6).

Answer 1

\(\bf \begin{array}{lllll}
&x_1&y_1&x_2&y_2\\
G&({\color{red}{ 8}}\quad ,&{\color{blue}{ 1}})\quad H&({\color{red}{ 8}}\quad ,&{\color{blue}{ -6}})
\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}}}\)
