Identify the equation as that of an ellipse or a circle. 9(x - 7)² + 4(y + 6)² = 36. A) ellipse B) circle

Question

Quizplus · Accepted Answer

The equation for a circle is (x - h)^2 + (y - k)^2 = r^2, where (h, k) is the center of the circle and r is the radius. The equation given is not in this form, so it cannot be a circle. Instead, it is in the form 9(x - 7)^2 + 4(y + 6)^2 = 36, which is the standard form for the equation of an ellipse.
