Question

Is the slope of (10,10) and (-5,5) = 0.3 ??

Answer 1

\(\bf \begin{array}{lllll}
&x_1&y_1&x_2&y_2\\
&({\color{red}{ 10}}\quad ,&{\color{blue}{ 10}})\quad &({\color{red}{ -5}}\quad ,&{\color{blue}{ 5}})
\end{array}
\\\quad \\

slope = {\color{green}{ m}}= \cfrac{rise}{run} \implies \cfrac{{\color{blue}{ 5}}-{\color{blue}{ 10}}}{{\color{red}{ -5}}-{\color{red}{ 10}}}\implies \cfrac{\cancel{ -5 }}{\cancel{ -15 }}\implies \cfrac{1}{3}\)

Answer 2

Oh okay, thank you!
