This table shows a proportional relationship between x and y. Find the constant of proportionality (r). Using the value for r, enter an equation in the form of y = rx.

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

Cbecause they are equal so that means it is the same on both sides? ! hope this
