Question

Which equation represents all points in a plane 5 units from point (3, 2)?

Answer 1

Answer: (x - 3)^2 + (y - 2)^2 = 5^2

Explanation:

This is a circle of radius 5 centered in the point (3,2)

We can write a circle as:

(x - a)^2 + (y - b)^2 = r^2

where the point (a, b) is the center and r is the radius, so our circle is:

(x - 3)^2 + (y - 2)^2 = 5^2
