Question
Let $P S$ be the median of the triangle with vertices $P$ $(2,2), Q(6,-1)$ and $R(7,3)$. The equation of the line passing through $(1,-1)$ and parallel to $P S$ is(A) $4 x-7 y-11=0$(B) $2 x+9 y+7=0$(C) $4 x+7 y+3=0$(D) $2 x-9 y-11=0$
Step 1
The median of a triangle divides the opposite side into two equal parts. Therefore, the coordinates of $S$ can be found by taking the average of the coordinates of $Q$ and $R$. Show more…
