Question

Find the slope of the line passing through the points (2,5) and (0,-4).

Answer 1

`\bf (\stackrel{x_1}{2}~,~\stackrel{y_1}{5})\qquad (\stackrel{x_2}{0}~,~\stackrel{y_2}{-4}) \\\\\\ slope = m\implies \cfrac{\stackrel{rise}{ y_2- y_1}}{\stackrel{run}{ x_2- x_1}}\implies \cfrac{-4-5}{0-2}\implies \cfrac{-9}{-2}\implies \cfrac{9}{2}\implies 4(1)/(2)`
