Question

A5,4 , B -3,-2, C 1,-8 are the vertices of triangle ABC .Find the equation of median AD and line parallel to AC passing through the point B

Answer 1

for eqn for median
calculate the mid point of BC
let it be (x1,y1)
and you have point which also lying on the median
now you have two points , calculate the slope of median and apply slope point form on it for any of the given points

for line passing through B parallel to AC
slope of AC = slope of Line thro' B
calculate slope of AC from given points
now you have slope of line through B and points of B
apply slope point form to it
