Answer 2

The number that the equation equals is the radius SQUARED. The square root of 16 is 4. So your RADIUS is 4. Hint: Diameter is 2 times your radius.

As for the points, the number with x is the x coordinate, and the number with y is the y coordinate.

Remember though, (x-9) means that the x coordinate is at POSITIVE 9, and (y+8) means the y coordinate is at NEGATIVE 8.
