Question

Find the slope of the line that passes through the pair of points (6.5, 10.5) and (–9.5, 7)

Answer 1

Use the slope formula, doesn't mater which point goes first as long as you are consistent in which point is which

Answer 2

\(\bf \begin{array}{lllll}
&x_1&y_1&x_2&y_2\\
&(6.5\quad ,&10.5)\quad &(-9.5\quad ,&7)
\end{array}
\\\quad \\

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