1.	Let PS be the mediûm of the triangle with verticesP(2,2), Q(6,-1) and R(7,3). Th equation of the linepassing through (1,-1) and parallel to PS is:
Answer» coordinate of S=(13/2,1) slope of ps=(1-2)/13/2 -2)=(-1)/(9/2)=-2/9 Eq. of the line passing through (-1,1) and parallel to PS is y-1=(-2/9)(x+1) 9(y-1)=-2x-2 9y-9+2x+2=0 2x+9y-7=0 thanks for answering right answer

Let PS be the mediûm of the triangle with verticesP(2,2), Q(6,-1) and R(7,3). Th equation of the linepassing through (1,-1) and parallel to PS is:

Answer»

coordinate of S=(13/2,1)

slope of ps=(1-2)/13/2 -2)=(-1)/(9/2)=-2/9

Eq. of the line passing through (-1,1) and parallel to PS is

y-1=(-2/9)(x+1)

9(y-1)=-2x-2

9y-9+2x+2=0

2x+9y-7=0
