Question

The slope of the line that passes through the point 2,4 and 3,8 is_____

Answer 1

`\bf (\stackrel{x_1}{2}~,~\stackrel{y_1}{4})\qquad (\stackrel{x_2}{3}~,~\stackrel{y_2}{8}) \\\\\\ slope = m\implies \cfrac{\stackrel{rise}{ y_2- y_1}}{\stackrel{run}{ x_2- x_1}}\implies \cfrac{8-4}{3-2}\implies \cfrac{4}{1}\implies 4`
