Question

Use the given information to write an equation of the circle. center at ​(-7​,-3​), radius 2

Answer 1

The equation of a circle is written as (x-h)^2 +(y-k)^2 = r^2

h and K are the center points of the circle and r is the radius.

replace the letters with the provided center and radius:

(x- (-7))^2 + (y- (-3))^2 = 2^2

Simplify:

(x+7)^2 + (y+3)^2 = 4
