why all those cluttery words? This is math, not English.
x^2+y^2+8x-8y-49 = 0
x^2+8x + y^2-8y = 49
Now complete the squares:
x^2+8x+16 + y^2-8y+16 = 49+16+16
(x+4)^2 + (y-4)^2 = 81
I think you can prolly take it from there, eh?
A circle has the equation x squared plus y squared plus 8 x minus 8 y minus 49 equals 0
Graph the circle using the center (h,k) and radius r. Find the intercepts, if any, of the graph.
