Question

The slope of the line passing through the points (50,1250000) and (60.800000)

Answer 1

$\bf (\stackrel{x_1}{50}~,~\stackrel{y_1}{1250000})\qquad (\stackrel{x_2}{60}~,~\stackrel{y_2}{800000}) \\\\\\ slope = m\implies \cfrac{\stackrel{rise}{ y_2- y_1}}{\stackrel{run}{ x_2- x_1}}\implies \cfrac{800000-1250000}{60-50} \\\\\\ \cfrac{-450000}{10}\implies -45000$
