I really don't get this lesson question:
Which statement is true for the circle?
http://learn.flvs.net/webdav/assessment_images/educator_geometry_v14/0800/0800_G8_Q29a.gif
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.

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
