The slope is $5$ $5$

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

$\frac{y_{2} - y_{1}}{x_{2} - x_{1}}$ $(y_2-y_1)/(x_2-x_1)$

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

$\frac{21 - 1}{2 - (- 2)}$ $(21-1)/(2-(-2))$

$\frac{20}{2 + 2}$ $20/(2+2)$

$\frac{20}{4}$ $20/4$

$5 \to$ $5 rarr$ This is the slope
