B is ( - 2 , - 4 ) and C is ( 6 , 12 ) .
.
Hence the mid point , say , D of BC is ( 6-2 / 2 , 12 - 4 / 2 )
.
D is ( 2 , 4 ) . and A is ( 2 , 18 ) .
.
Hence the median AD will have the equation
.
y - 1 8 / 18 - 4 = x - 2 / 2 - 2
.
y - 1 8 / 14 = x - 2 / 0
.
Hence x - 2 = 0 is the equation of the median AD .

midpoint of BC = (2, 4 )
the line containing the median from A to be is x = 2.

Midpoint AB = (0,7)
Midpoint AC = (4,15)
Midpoint BC = (2,4)
Median from A to BC
A (2,18) to midpoint of BC (2,4)
Equation of line through (2,18) and (2,4)
equation : x=2
