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

---------------- = slope

change in x

-5 - 1

-------- {subtracted y-coordinates over subtraction of x-coordinates}

2 - (-2)

-6

--- {subtracted}

4

**= -3/2**{simplified}
