This is the equation for a circle. The center of the circle is the source and the outside of the circle is the radio signal. x-4 notes the x-coordinate (or "h") of the center of the circle, and y-2 notes the y-coordinate (or "k") of the center of the circle. Therefore, the center of the circle sits at (4,2). The formula for a circle is (x-h)^2 + (y-k)^2 = r^2. So the 169 is the square of the radius, which is 13. So the source sits at (4, 2) and the signals are at a radius length of 13, or 13 units from the center.
Given :
- 2 - 1/2y = 0

- 2 - 1/2y = 0
- 1/2y = 2
- y = 2*2
- y = 4
- y = 0x + 4
18 because 4 is multiplied by 3 to get 12 and 6x3 is 18
