Answer 1

Which statement is true for the circle?

Its center is atthe ordered pair of ,(1/2, -1), and the radius is (-5/2) units.

Its center is atthe ordered pair of (-1/2, 1), and the radius is 5/2 units.

Its center is atthe ordered pair of (1/2, - 1), and the radius is 5/2 units.

Its center is atthe ordered pair of (-1/2, 1), and the radius is -5/2 units.

Answer 2

the third answer is correct. The 25/4 is the same as the radius squared, so the radius must be 5/2. The first term, (x-1/2)^2 tells you that the circle is centered at (1/2,y) the second term, (y+1)^2 tells you that the y center is at negative 1.
