Question 87742
the equation to find slope is y2-y1 over x2-x1. since your points are (-1,4) and (2,-1) you plug in the numbers. So it should look like -1-4 over 2+1. you then solve it across and it equals -5/3.
y2 - y1
--------  =  slope
x2 - x1


-1-4           
-----          
2+1     

answer: -5/3
