Question

The equation of the median of the triangle with vertices (4 3) (-2 3) (1-2) passing through (-2,3)
1) 5x+9y+17=0
2) 9x-5y-11=0
3) 5x+9y-17=0
4) 5x-9y+13=0
​

Answer 1

Answer:

Correct option is

D

2x+9y+7=0

Since S is mid point of Q and R

∴S=(27+6,23−1)=(213,1)

Slope of PS=m=x2−x1y2−y1=2−2132−1=9−2

Equation of the line passing through (1,−1) and parllel to PS is 

y−(−1)=9−2(x−1)

y+1=9−2x+2

⇒9y+9+2x−2=0

⇒2x+9y+7=0
