Question

What is the slope of the line passing through the points (3,3) and (5,7) a. 2 b. 1/2 c. -1/2 d. -2

Answer 1

`\bf (\stackrel{x_1}{3}~,~\stackrel{y_1}{3})\qquad (\stackrel{x_2}{5}~,~\stackrel{y_2}{7}) \\\\\\ slope = m\implies \cfrac{\stackrel{rise}{ y_2- y_1}}{\stackrel{run}{ x_2- x_1}}\implies \cfrac{7-3}{5-3}\implies \cfrac{4}{2}\implies 2`
