Answer:
Center: 2, -3
Radius: 7
Step-by-step explanation:
The center of the circle is defined by the numbers subtracted from the variables. The x value for the center is 2, since it is x - 2, and the y value is -3, because y - -3.
The radius is equal to the square root of the constant on the other side.
The square root of 49 is 7.
Y = -7
or
x = 10
or
y = x - 13
there can be endless answers
