PLZ HELP ASAP 20 POINTS PLZ BY THIS HOUR. Determine the equation of the circle and justify your reasoning,
A. The equation of the circle is (x + y)? = because the curvature of the
circle is formed by a quadratic relationship.
B. The equation of the circle is x + y = r because the radius of the circle is
always equal to the sum of the x and y coordinates.
C. The equation of the circle is x + y = because the Pythagorean
Theorem can be used to describe all points equidistant from the origin
with a radius of r.
D. The equation of the circle is x2 + y = r because the distance formula can
be used to determine all points equidistant from the origin with a radius
of r.
