Question

What is the slope of the line that passes through the points (8, 2) and (9,3)? Write
your answer in simplest form.

Answer 1

$\bf (\stackrel{x_1}{8}~,~\stackrel{y_1}{2})\qquad (\stackrel{x_2}{9}~,~\stackrel{y_2}{3}) ~\hfill \stackrel{slope}{m}\implies \cfrac{\stackrel{rise} {\stackrel{y_2}{3}-\stackrel{y1}{2}}}{\underset{run} {\underset{x_2}{9}-\underset{x_1}{8}}}\implies \cfrac{1}{1}\implies 1$
