Question

Does (2, 1) lie on the line x-2y =0?

• A. Yes
• B. No
• C. Maybe
• D. Cannot be determined

Answer 1

The correct option is A

Yes

To check whether a point lies on a line substitute the point's x and y coordinates In the line equation.If it satisfies the equation then it lies on the line. Putting the values in the given equation we get 2-2(1)=0. Hence, the given point, (2,1), lies on the line.
