Question

The point (−7, 1) is on a circle with center (−7, 6). Write the standard equation of the circle.

Answer 1

Explanation:

(x + 7)² + (y – 6)² = 25

Answer 2

- The standard Cartesian form for the equation of a circle is: ... Substitute the point (−1,−2) into equation [2] and solve for r: (−1−3)2+(−2−5)2=r2. (−4)2+(−7)2=r2 ... Note: Please understand that I write the right side as (√65)2 , instead ... What conic section does the equation 2x2+4xy+6y2+6x+2y=6 represent?
