Question

What is the slope of the line passing through (5,-1) and (5,3)?

A) 0 B) undefined C) 1/5 D) 5

Answer 1

\(\bf \begin{array}{lllll}
&x_1&y_1&x_2&y_2\\
&({\color{red}{ 5}}\quad ,&{\color{blue}{ -1}})\quad &({\color{red}{ 5}}\quad ,&{\color{blue}{ 3}})
\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}}}\)

Answer 2

yup

Answer 3

B) Undefined
