Find the equations of the wedians of the triangle with vertex coordinates J(2,5), K(4,-1), andL(-2,-5)

There are 3 medians (wedians ?) so you have 3 identical questions.

I will do one:
Median form J to KL
midpoint of KL is (1,-3)
slope of median = (5 - (-3))/(2-1)
= 8

equation : y = 8x + b
but point (2,5) lies on it, so
5 = 8(2) + b
b = -11

median equation: y = 8x - 11

do the other two the same way.
