$m = \frac{y_{2} - y_{1}}{x_{2} - x_{1}} = \frac{2 - - 1}{- 9 - 1} = \frac{3}{- 10}$ $m=(y_2-y_1)/(x_2-x_1)=(2--1)/(-9-1)=3/-10$

Divide the change in y which is y2-y1 by the change in x i.e x2-x1 and then simplify

What is the slope of the line passing through the following points: (1,-1) , (-9,2)(1,−1),(−9,2) (1,-1) , (-9,2)?
