Question
The locus of the centres of the circles such that the point (2, 3) is the mid point of the chord 5x + 2y = 16 is -
Options
A.2x - 5y + 11 = 0
B.2x + 5y - 11 = 0
C.2x + 5y + 11 = 0
D.none
Solution
Centre of circles lie on the perpendicular bisector
⇒
locus of P(h, k) is 2x - 5y + 11 = 0
⇒
locus of P(h, k) is 2x - 5y + 11 = 0
