Question

Find the equation of the diameter of the circle given by x²+y²-12x+4y+6=0

Answer 1

$x^2-12x+y^2+4y+6=0\\\\(x-6)^2-6^2+(y+2)^2-2^2+6=0\\\\(x-6)^2+(y+2)^2=34\\\\Center=(6,-2)\\\\Let\ equation\ of\ Diameter\ be: y=mx+c\\\\(6,-2)\ is\ on\ the\ line\\\\-2=m\ 6+c,\ \ =>\ c=-6m-2\\\\Equation\ of\ diameter=y=mx-6m-2$

This is a parametric equation for the diameter of the circle.  Given a value of m, you get the equation of diameter with that slope.
