In this case, we'll have to carry out several steps to find the solution.
Step 01:
Data
Graph
Center = ( - 7 , 2)
Radius = 2
equation of the circle = ?
Step 02:
equation of the circle
(x - h) ² + (y - k) ² = r ²
( h , k) = ( - 7 , 2)
r = 2
( x - (-7)) ² + (y - 2)² = 2 ²
(x + 7)² + (y - 2)² = 4
The answer is:
The equation of the circle is (x + 7)² + (y - 2)² = 4
