Question

Which of the following circles have their centers in the third quadrant?

Check all that apply.
A. (x + 9)2 + (y + 12)2 = 36
B. (x + 16)2 + (y + 3)2 = 17
C. (x + 3)2 + (y - 6)2 = 44
D. (x + 14)2 + (y - 14)2 = 84

Answer 1

The third quadrant has both a negative x and y coordinate. To find this, find the ones with both x+a number and y+a number since the form is
\((x-h)^2+(y-k^2)=r^2\)
