Question 1183671: What is an equation that relates all the x- and y- coordinates of points that lie
on ⊙M with a radius of 5, which is centered at the origin? Answer by Edwin McCravy(20055) (Show Source):
You can put this solution on YOUR website! What is an equation that relates all the x- and y- coordinates of points that
lie on ⊙M with a radius of 5, which is centered at the origin?
Let P(x,y) be an arbitrary point on circle M. The right triangle with
legs x and y, hypotenuse 5, and vertex P(x,y) can be drawn anywhere on the
circle. So the equation that holds for all points on the circle is the
Pythagorean theorem, using x and y for the legs and 5 for the hypotenuse.
x2 + y2 = 52
or
x2 + y2 = 25
