Y 2 - y 1 x 2 - x 1 and reduce the resulting fraction to the simplest form. The general equation of a circle is where A C and have the same sign. Now substitute these values in that equation.
What is the General Form Linear Equation.
It shows all the important information at a glance. This form of the equation is helpful since you can easily find the center and the radius. X - h 2 y-k 2 r 2. Using the center point and the radius you can find the equation of the circle using the general circle formula x-h x-h y-k y-k rr where hk is the center of your circle and r is the radius.
