Question

Find the equation of the circle which has A(1, 3) and B(4, 5) as opposite ends of a
diameter. Find also the equation of the perpendicular diameter.
​

Answer 1

Answer:

Use diametric form of circle : ( x - x1)( x - x2) + ( y - y1)( y - y2) = 0

( x - 1)( x - 4) + ( y - 3)( y - 5) = 0

Eqn of Circle : x²+ y² - 5x - 8y +19 = 0
