Question

The point of the form (a, – a) always lies on the line ______.

विकल्प

• x = a

• y = – a

• y = x

• x + y = 0

Answer 1

The point of the form (a, – a) always lies on the line x + y = 0.

Explanation:

x + y = a + (– a)

= a – a  ...[Since, give point is of the form (a, – a)]

= 0

Hence, the point (a, – a) always lies on the line x + y = 0.
