Has a diameter with end points A(-3,2) and B(7,4)

Question

Give me the solution

Answer 1

Ask the question: you want the equation of this circle.

 

First, find the center,  M, a.k.a. midpoint of AB, so you will use the Midpoint Formulas.  M will be (h,k).

Then find the radius, using the Distance formula for AM.

Then substitute h, k and r into the general equation for a circle of radius r, center (h,k).

That formula is in your book as well as, I hope, in your head.
