Answer:
- 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?
