Question 40683: how do you estimate slope?
Answer by checkley71(8403)   (Show Source):
You can put this solution on YOUR website! TO FIND THE SLOPE OF A LINE THROUGH TWO POINTS EXPRESSED AS X&Y SUCH AS
(X1,Y1)&(X2,Y2) THE SLOPE IS FOUND BY SUBTRACTING THE Y1 POIT FROM THE Y2 POINT ANSD DIVDING THIS ANSWER BY THE SUBTRATION OF THE X1 POINT FROM THE X2 POINT
THIS IS AN EXAMPLE: WHERE X1=0, Y1=6, X2=4, Y2=-4
(0,6)(4,-4) GIVES A SLOPE OF (-4-6)/(4-0) OR -10/4 OR SLOPE = -2.5
