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