How do you write an equation for a circle with (-10 , 0) to (-16 , -10) as a diameter?
The equation is
Start by finding the length of the diameter using the distance formula.
We will now find the radius using the formula
Now, let's find the centre of the circle. We can do this using the midpoint formula.
We can now write the equation of the circle. The form
Substituting, we get:
