Question

I need the slope of the line passing through the two points (-1,1) (1-3)

Answer 1

The slope can be found as follows:

$\begin{gathered} m=\frac{y2-y1}{x2-x1} \\ _{\text{ }}where\colon \\ (x1,y1)=(-1,1) \\ (x2,y2)=(1,-3) \\ so\colon \\ m=\frac{-3-1}{1-(-1)}=\frac{-4}{2}=-2 \end{gathered}$

Answer:

-2
