Question

a point on the line y=x at a distance of 2 unit from the origin is

Answer 1

X=2 units and y=2 units or x=-2 units and y=-2units

Answer 2

Answer:

let point be (h,k),then

h^2+k^2=4.................…......................................(i)

and h=k. {point lies on line y=x}...........(ii)

on solving ,h=+√2 or - √2. and

k=+√2 or -√2

hence the point is (√2,√2) or (-√2,-√2)
