A slope is a ratio of the change in y divided by the change in x

First find the change in the $y$ value. Take

$4 - (-2) = 6$ as the change in $y$ .

Next find the change in the $x$ value. Take

$-16 - 5 = -21$ as the change in $x$

Then divide the change in the $y$ value by the change in the $x$ value, so

$"slope" = (-21)/6 = (- 7 xx cancel(3))/(2 xx cancel(3))$

A factor of three can be divide out leaving a slope of

$"slope" = - 7/2$
