Question

Which of the following lines passes through the origin? 

(a) x = 2 

(b) y = 3 

(c) y = x + 2 

(d) 2x – y = 0

Answer 1

Correct option is : (d) 2x – y = 0

Any line passing through origin is of the form y = mx or ax + by = 0. 

Here in the given option, 2x – y = 0 is in the form ax + by = 0. 

∴ Option (d) is the correct answer.
