Ailani draws a map of her local town. She places the town hall at the origin of a coordinate plane and represents a lake
with a circle drawn on the map. The center of the lake is 19 miles east and 3 miles south of the town hall, and the
radius of the lake is 0.5 miles.
If the positive x-axis represents east and the positive y-axis represents north, which equation represents the lake?
(x + 19)2 + (y – 3)2 = 0.5
(x – 19)2 + (y + 3)2 = 0.5
(x + 19)2 + (y – 3)2 = 0.25
(x – 19)2 + (y + 3)2 = 0.25
