Coordinate Geometry Question 31
Question: The ratio in which x-axis divides the join of the points (2, -3) and (5, 6) is
Options:
A) 2 : 1
B) 1: 2
C) 2 : -1
D) None of these
Show Answer
Answer:
Correct Answer: B
Solution:
Let ratio be k : 1 and coordinates of x-axis are $ (a,0). $ Therefore $ 0=\frac{k\times 6+1\times (-3)}{k+1}\Rightarrow k=\frac{1}{2} $
Hence the ratio is 1 : 2. Aliter: Apply the formula given in the theory part, the required ratio is $ -( \frac{-3}{6} ) $ or 1 : 2.
