$m = \frac{y_{2} - y_{1}}{x_{2} - x_{1}} = 4$ $m=(y_2-y_1)/(x_2-x_1) = 4$

To find the slope of two points, we need to use the following slope formula;

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

where m is slope and $(x_{1}, y_{1})$ $(x_1,y_1)$ and $(x_{2}, y_{2})$ $(x_2,y_2)$ are the co-ordinates of the points.

In this question let's assume that

$(x_{1}, y_{1}) = (- 1, - 6)$ $(x_1,y_1) = (-1,-6)$ and $(x_{2}, y_{2}) = (1, 2)$ $(x_2,y_2)=(1,2)$

Now plug the given values in the formula, we get

$m = \frac{2 - (- 6)}{1 - (- 1)} = \frac{2 + 6}{1 + 1} = \frac{8}{2} = 4$ $m=(2-(-6))/(1-(-1)) = (2+6)/(1+1) = 8/2 = 4$

Hence the slope of points is 4.
