Given the 2 points (3,1) and (4,6) what is the slope of the line?

zmey [24]

$\bf \begin{array}{ccccccccc}
&&x_1&&y_1&&x_2&&y_2\\
% (a,b)
&&(~ 3 &,& 1~) 
% (c,d)
&&(~ 4 &,& 6~)
\end{array}
\\\\\\
% slope = m
slope = m\implies 
\cfrac{\stackrel{rise}{ y_2- y_1}}{\stackrel{run}{ x_2- x_1}}\implies \cfrac{6-1}{4-3}\implies \cfrac{5}{1}\implies 5$
