Question 163787
There is a formula for the slope between two points that looks like this:
{{{m= (rise)/(run) = (y[2] - y[1])/(x[2]-x[1]) }}}
.
Since they gave you:
(6,7) and (2,-8)
.
then
(x[1],y[1])=(6,7)
(x[2],y[2])=(2,-8)
.
Plugging it in:
{{{m= (rise)/(run) = (y[2] - y[1])/(x[2]-x[1]) }}}
{{{m= (rise)/(run) = (-8 - 7)/(2-6) }}}
{{{m= (rise)/(run) = (-15)/(-4) }}}
{{{m= (rise)/(run) = -15/4 }}}
