The slope is $5$

To find the slope using two points, divide the difference of the y-coordinates by the difference of the x-coordinates

$(y_2-y_1)/(x_2-x_1)$

In this case, $y_2$ would be 21, $y_1$ would be 1, $x_2$ would be 2, and $x_1$ would be -2

$(21-1)/(2-(-2))$

$20/(2+2)$

$20/4$

$5 rarr$ This is the slope
