Question

Graph the circle x2 + y2 + 10x + 6y + 18 = 0.

Answer 1

Answer:

  see below for a graph

Step-by-step explanation:

Completing the square for x and y terms can help you put this in the standard form.

  (x^2 +10x) +(y^2 +6y) = -18

  (x^2 +10x +25) +(y^2 +6x +9) = -18 +25 +9 . . . . add square of half linear coefficient

  (x +5)^2 +(y +3)^2 = 16 . . . . . . . circle centered at (-5, -3) with radius 4

Answer 2

Answer:

The graph is formed from the equation

(X+5)^2. + (Y+3)^2. = 16
