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

Answer:

-2
