Question

Look at the graph.
Which equation best represents the circle in the graph?

options:
(x + 1)2 + (y - 4)2 = 9

(x + 1)2 + (y + 4)2 = 9

(x - 1)2 + (y - 4)2 = 9

(x - 1)2 + (y + 4)2 = 9

Answer 1

Reallllllly cheap way to get the answer for this one. Your center of your circle is in the first quadrant, where both x and y have to be positive. That means both the x and y terms are x- and y -. Only one of your answers has that, lol.

Answer 8

u should be online more often because u explain good and its easier to find the answer
