How do you write the equation of the circle whose diameter has endpoints (-1,0) and (6,-5)?
then, its eqn. is given by,
Applying this, we can immediately get the eqn. of circle as,
Knowing that the mid-pt. of a diameter is the Centre of the Circle,
we get the Centre
Now, the pt.
the Centre, the dist.
Hence, the eqn of the circle is
