Question

Find the slope of the line joining the points (4,8)and(5,-12)

Answer 1

Given that ,

The two points are (4,8) and (5,-12)

We know that , the slope of line is given by

$\large \sf\fbox{Slope \: (m) = \frac{ y_{2} - y_{1}}{ x_{2} - x_{2}} }$

Thus ,

$\sf \mapsto m = \frac{ - 12 - 8}{5 - 4} \\ \\ \sf \mapsto m = \frac{ - 20}{1} \\ \\ \sf \mapsto m = - 20$

$\therefore\sf \underline{The \: slope \: of \: the \: line \: is -20}$
