Posted by :(plz help on .
how do i find the slope of line AB if A`s coordinates are(4,3) and B`s coordinates are (2,1)

math 
helper,
A(4,3) and B(2,1)
If you have points A(x1,y1) and B(x2,y2)
Slope m = (y2  y1)/(x2  x1) 
math 
:(plz help,
so i just have to do (13)/(3(4)

math 
helper,
m = (13)/(2(4)
You had 3, should be 2
