A triangle has vertices J(-4,3), K(2,-3), and L(8,3). Find the equation of the line containing the median from vertex K
--------------
The median from K is to the midpoint of side JL.
---
Find the x and y of the midpoint:
For x: (-4+8)/2 = 2
For y: (3+3)/3 = 3
Midpoint is P(2,3)
-----
Find the slope of the line thru K & P
Slope m = diffy/diffx
m = (-3+3)/(2-2) = undefined, parallel to the y=axis
---> x = 2 is an equation of the line.
