Find the slope of the line

9/17/2020

What is the slope of the line through (-2,1) and (2,-5) in the standard (x,y) coordinate plane?

change in y
---------------- = slope
change in x

-5 - 1
-------- {subtracted y-coordinates over subtraction of x-coordinates}
2 - (-2)

-6
--- {subtracted}
4

= -3/2 {simplified}
