If x ₁, x ₂, x ₃ and y ₁, y ₂, y ₃ are both in G.P. with the same common ratio, then the points ( x ₁, y ₁ ), ( x ₂, y ₂ ) and ( x ₃ . , y ₃ )

Options

  1. Aare vertices of a triangle
  2. Blie on a straight line
  3. Clie on an ellipse
  4. Dlie on a circle

Correct answer

B. lie on a straight line

Step-by-step solution

Taking co-ordinates as ( x r , y r ) ;( x , y ) &( xr , yr ) . Above coordinates satisfy the relation y = mx Therefore lies on the straight line.
