Question

Can somebody explain how the slope formula is used in general

Answer 1

formula for slope = y2-y1/x2-x1, u use it to find the slope of the line between 2 points. example if u need to find the slope of (1,2) and (4,5), plug in 5 for y2, 2 for y1, 4 for x2, and 1 for x1. ur answer would be 3/3, or a slope of 1

Answer 2

are you trying to find the slope or to find the equation of the line with those points?

Answer 3

\(\bf \begin{array}{lllll}
&x_1&y_1&x_2&y_2\\
&({\color{red}{ 1}}\quad ,&{\color{blue}{ 2}})\quad &({\color{red}{4}}\quad ,&{\color{blue}{ 5}})
\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}}}\)

that would give you the slope between the points
