Straight Line Question 155
Question: Let A, (2,-3) and B (-2, 1) be the vertices of a triangle ABC. If the centroid of this triangle moves on the line $ 2x+3y=1, $ then the locus of the vertex C is the line
Options:
A) $ 2x+3y=9 $
B) $ 2x-3y=7 $
C) $ 3x+2y=5 $
D) $ 3x-2y=3 $
Correct Answer: A $ \Rightarrow 2( \frac{x}{3} )+3( \frac{y-2}{3} )=1 $ $ \Rightarrow 2x+3y=9 $ The above equation is the locus of the vertex c.
