The equation (x + 6)2 + (y + 4)2 = 36 models the position and range of the source of a radio signal. Describe the position of the source and the range of the signals
This is the equation of a circle: (x-h)² + (y-k)² = r² (h, k) is the center of the circle, and r is the radius of the circle.
I think your source is (-6,-4) and your range is 6
