Question

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 $(x_3,y_3)$

• A. Lie on straight line
• B. Lie on an ellipse
• C. Lie on a circle
• D. Are vertices of a triangle

Answer 1

The correct option is A Lie on straight line

Taking co-ordinates as $(\frac{x}{r},\frac{y}{r});(x,y)and(xr,yr)$
Above points lie on a straight line
