Question

What is the slope of the line that goes through the ordered pairs (7,2) and (4,6)?

Answer 1

$(\stackrel{x_1}{7}~,~\stackrel{y_1}{2})\qquad (\stackrel{x_2}{4}~,~\stackrel{y_2}{6}) ~\hfill \stackrel{slope}{m}\implies \cfrac{\stackrel{rise} {\stackrel{y_2}{6}-\stackrel{y1}{2}}}{\underset{run} {\underset{x_2}{4}-\underset{x_1}{7}}}\implies \cfrac{4}{-3}\implies -\cfrac{4}{3}$
