Rewrite the equation for this circle in Standard Form: x+14x + y+16y+ 77 = 0 Standard Form: 0-0 Remember. The standard form for a circle is (x - H)2 + (y - K) = R. Center: Radius: Do not use decimal approximations. Enter radicals such as 15 as 'sqrt(15)' instead of using rational exponents. You do not need to reduce your radicals for this problem.
