The temperature in indianapolis was-4°f at 7: 00 am. the temperature rose 3°f by noon. what was the temperature at noon? use a number line to find the answer

I believe that it would be -1

X^2 - 4x +(4/2^2) + y^2 + 8y + (8/2^2) = -4 + (4/2^2) + (8/2^2)(x + 2)^2 + (y + 4)^2 = -4 + 4 + 16your center is (-2, -4) and the radius is the sqrt of -4 + 4 + 16 which is 4
