Posted  10/16/2007 : 18:56:55 Please help me fine and equation for the left half of the circle given by (x+2)+y=9
I foiled the x+2 and solved for x. the answer I got was x= y4x5 but I didn't know if it was ok to still have the x in the answer.

Skeeter, isn't that just a translation of the entire circle to the left? If she wants the left half, should there not be boundaries defined?
{(x2) + y^=9; 5<=x<=2}
plot some points using my last equation and see the result for yourself.

Posted  10/16/2007 : 19:28:50 (x + 2) + y = 9
(x + 2) = 9  y
x + 2 = (9  y)
x = [2 + (9  y)]
