The correct option is B x2+y2−7x−8y−874=0
Given equations are 2y=4x−6 and y2=16x
As the line and curve are intersecting at points A and B,
solving them, we get
(2x−3)2=16x⇒x2−7x+94=0 ⋯(1)
This is quadratic equation in x.
Again, solving both the equations, we get
y2=16×(y+32)⇒y2−8y−24=0 ⋯(2)
This is quadratic equation in y.
Therefore, the equation of circle whose diameter is AB is given by adding equations (1) and (2)
x2+y2−7x−8y−874=0
