Question

What is the slope of a line with endpoints at (3,4) and (2,5)?

Answer 1

Slope is 1 because the equation for slope is y-y/x-x substitute the numbers in to get 4-5/3-2 and you get -1/-1 and the negatives cancel out to get 1/1 and that can be written as 1

Answer 2

$\bf (\stackrel{x_1}{3}~,~\stackrel{y_1}{4})\qquad (\stackrel{x_2}{2}~,~\stackrel{y_2}{5}) \\\\\\ slope = m\implies \cfrac{\stackrel{rise}{ y_2- y_1}}{\stackrel{run}{ x_2- x_1}}\implies \cfrac{5-4}{2-3}\implies \cfrac{1}{-1}\implies -1$
