Find the slope of the line through each pair of points. (1/2, 2/3) and (3/2, 5/3)

solniwko [45]

$\bf (\stackrel{x_1}{\frac{1}{2}}~,~\stackrel{y_1}{\frac{2}{3}})\qquad (\stackrel{x_2}{\frac{3}{2}}~,~\stackrel{y_2}{\frac{5}{3}}) \\\\\\ slope = m\implies \cfrac{\stackrel{rise}{ y_2- y_1}}{\stackrel{run}{ x_2- x_1}}\implies \cfrac{~~\frac{5}{3}-\frac{2}{3}~~}{\frac{3}{2}-\frac{1}{2}}\implies \cfrac{~~\frac{3}{3}~~}{\frac{2}{2}}\implies \cfrac{1}{1}\implies 1$
