I really don't get this lesson question:
Which statement is true for the circle?

Its center is at the ordered pair of 1 over 2, minus 1, and the radius is minus five over two units.
Its center is at the ordered pair of minus 1 over 2, 1, and the radius is five over two units.
Its center is at the ordered pair of 1 over 2, minus 1, and the radius is five over two units.
Its center is at the ordered pair of minus 1 over 2, 1, and the radius is minus five over two units.

Best ResponseYou've already chosen the best response.1a radius is always positive

Best ResponseYou've already chosen the best response.1that rules out 2 of your choices

Best ResponseYou've already chosen the best response.0so it's either B or C, but I still don't know which

phi

Best ResponseYou've already chosen the best response.1the (x,y) pair at the center will make the (xa)^2 and (yb)^2 terms zero does that make sense?

phi

Best ResponseYou've already chosen the best response.1usually they say (xh)^2 + (yk)^2 = r^2 and the center is at (h,k) with radius r

Best ResponseYou've already chosen the best response.0how do we get h and k?

phi

Best ResponseYou've already chosen the best response.1so if you see (x 1/2) that means the x value of the center is +1/2

phi

Best ResponseYou've already chosen the best response.1in this case you match your equation to the "generic" one match (xh)^2 + (yk)^2 = r^2 (x1/2)^2 + (y + 1)^2 = 25/4

phi

Best ResponseYou've already chosen the best response.1matching yk to y+1 you have to rewrite y+1 as y  (1) now you see y  k matches y  (1) and k is 1

phi

Best ResponseYou've already chosen the best response.1or remember that you want the y value that makes (y+1)^2 zero. that would be y= 1

Best ResponseYou've already chosen the best response.0then it's C? Right?
