Question

The possible co-ordinates of point R which is at a distance of 19 units from point S having co-ordinate 12 are
(A) 31,-7.
(B) -31,7
(C) 31, 7
(D) -31,-7​

Answer 1

Answer:

Required collection of Points are

${(x - 1)}^{2} + {(y - 2)}^{2} = {19}^{2}$

now we check which option satisfied above equation,

Here option A (31, —7) satisfied so possible Co-ordinate of point R is (31, —7)

Answer 2

(A) 31,-7.

(B) -31,7

(C) 31, 7

(D) -31,-7
