Question

What is the standard form of equation of a circle with center at (-2, -3) and passing through the point (-2, 0)?

A) (x + 2)2 + (y + 3)2 = 9
B) (x − 2)2 + (y − 3)2 = 16
C) (x − 2)2 + (y − 3)2 = 4
D) (x + 2)2 + (y + 3)2 = 16
E) (x − 2)2 + (y + 3)2 = 9

Answer 2

Standard circle -

(x - h)^2 + (y - k)^2 = r^2

the center is point (h,k) and radius r

Answer 3

The radius here is the distance from center point to the other point on the circle

Answer 4

(x-2)^2+(y-3)^2 is the equation i use?

Answer 5

Careful with that, the center point has both negative values for h and k, minus a negative is addition

Answer 6

(x - (-2))^2
