<PRE><B>Question 845156</B>
To find the slope of a line given two points you use the formula 

m = y2-y1/x2-x1.


So, given the points A(8,2) and B(4,1) we will say that 8 = x1 and 2 = y1

4 = x2 and 1 = y2.

Then all you do is plug in the values for the formula and you will find the slope.

m = 1-2/4-8 = -1/-4 = 1/4

Therefore the slope is 1/4.
