Test your problem-solving accuracy on this official-caliber item. Select an answer choice to check your reasoning instantly.
Identify the quadratic form: consider converting to vertex form \( y = a(x-h)^2 + k \) or using \( x = -rac{b}{2a} \) to find the line of symmetry.
Desmos Tactical Shortcut: Plot the left-hand side and right-hand side as separate equations (e.g. \( y_1 = f(x) \) and \( y_2 = g(x) \)). Click the intersection points directly to read exact coordinates.
This is a beautiful, high-level coordinate geometry problem. To solve anything involving the equation of a circle on the SAT, your very first instinct must be to 'Complete the Square' to get it into standard form: \( (x - h)^2 + (y - k)^2 =...
