**Bosnian**, Sunday, February 13, 2011 at 4:39amThis is the formula for finding the slope of a line.

m is the variable used for the slope

m=(y2-y1)/(x2-x1)

m=[(5-(-10)]/(-3-4)

m=(-15)/(-7)

m=15/7 Becose ratio of two negative nubers is positive number

[(5-(-10)]=5+10=15

m=15/(-7)=(-15)/7

(-3, -10) and (4, 5).

m=(y2-y1)/(x2-x1)

m=[5-(-10)]/[4-(-3)]

m=15/7
