Determine the slope (9,2) and (3,-8)

Oxana [17]

$\bf \begin{array}{ccccccccc}
&&x_1&&y_1&&x_2&&y_2\\
% (a,b)
&&(~ 9 &,& 2~) 
% (c,d)
&&(~ 3 &,& -8~)
\end{array}
\\\\\\
% slope = m
slope = m\implies 
\cfrac{\stackrel{rise}{ y_2- y_1}}{\stackrel{run}{ x_2- x_1}}\implies \cfrac{-8-2}{3-9}\implies \cfrac{-10}{-6}\implies \cfrac{5}{3}$

The constant of proportionality is the slope of the line.

The slope is the change in y over the change in x

Using two pints on the line:

Slope = (3-0) / (1-0) = 3/1 = 3

The answer is 3
