Write an equation representing a pair of lines through the point `(a , b)` and parallel to the coordinate axes.

A

`(x-a)(y+b)=0`

B

`(a-b)(y-a)=0`

C

`(x-a)(y-b)=0`

D

`(x+a)(y-b)=0`

Text Solution

Verified by Experts

The correct Answer is:
C
The equations of lines parallel to the coordinate axes and passing through (a,b) are x=a and y=b . So, their combined equation is (x-a)(y-b)=0
