Smiley Face

[Chuck Norris]

Hi, I'm trying to draw a smiley face on a graphics calculator without conics, however I am stuck on how to make y the subject of a function in which the function is a conic and is essentially a circle. How do you make y the subject of the equation?

 

(x-5)^2+(y+5)^2=4

 

^ denotes to the power of.

put the x term on the other side (it gains a - sign)

 

take the square root of both sides

 

subtract the constant from both sides

Thanks, however that seems too obvious (how could I overlook that?). If any problems arise from your method I'll post.
