Question

The point of the form (a, a) always lies on:
(a) x-axis (b) y-axis (c) on the line y = x
(d) on the x + y=0

Answer 1

Answer:

option C

Step-by-step explanation:

option a ) for a point to remain in x-axis , it's coordinates must be (x,0)

option b) for a point to remain in y-axis it's coordinates must be (0,y)

option c ) for a point to remain in line y=x , it's coordinates must be (a,a), and hence this is answer

option d ) for a point to remain in line 'x+y=0'

, it's coordinates must be either (a,-a) or (-a,a)
