Complete the square to rewrite the following equation. Identify the center and radius of the circle. You must show all work and calculations to receive credit x^2 - 4x + y^2 + 8y = -4​

x ² - 4x + y ² + 8y = -4

(x ² - 4x + 4) + (y ² + 8y + 16) = -4 + 4 + 16

(x - 2)² + (y + 4)² = 16

(x - 2)² + (y + 4)² = 4²

which is the equation of a circle centered at (2, -4) and with radius 4.

(0,,,0)

step-by-step explanation:

the table of x and y values is shown in the attached pic(part of question)

we have to decide according that graph

given points are (0, 0) (–1, 0), (2, 0)

when we graph these points on graph they show an increasing line as shown in the attached pic
