 Question 555063: what is the equation of a circle with center (-6,4) passing through the points (9,4).? Hope to hear from you soon. Thank you and Godbless! I promise to pay your kindness in any way that i can.Answer by KMST(2478)   (Show Source): You can put this solution on YOUR website!The radius is the distance between the two points given. They have the same y coordinate, so the distance is the difference between the x coordinates A circle is the collection of all the points at a certain distance from the center point. Your circle is the collection of all the points at a distance of 15 from the center point (-6, 4). The distance squared would be . The square of the distance from a point (x, y) to (-6, 4) is . If that point is in the circle of the problem, . That equation is the equation of the circle with center (-6,4) passing through the points (9,4). If a point is in that circle its coordinates will satisfy that equation. If the coordinates of a point satisfy that equation, the point is in the circle.
