A) (1, -2)
B) (1, 4)
C) (1, 2)
D) (1, -4)
Correct Answer: D
Solution :
Equation of circles is \[{{S}_{1}}={{x}^{2}}+{{y}^{2}}+2x-3y+6=0\] ..... (i) \[{{S}_{2}}={{x}^{2}}+{{y}^{2}}+x-8y-13=0\] ..... (ii) \[\therefore \] Equation of common chord is \[{{S}_{1}}-{{S}_{2}}=0\] \[\Rightarrow x+5y+19=0\] .....(iii) and out of the four given points only point (1, ?4) satisfies it.You need to login to perform this action.
