A circle has the equation x^2+y^2-x-4y+4=0
Graph the circle using the center(h,k) and radius r. find the intercepts of the graph.
-----------------------
x^2+y^2-x-4y = -4
Complete the square for x and y terms
x^2 - x + y^2 - 4y = -4
x^2 - x + 1/4 + y^2 - 4y + 4 = -4 + 1/4 + 4 = 1/4
%28x+-+1%2F2%29%5E2+%2B+%28y+-+2%29%5E2+=+%281%2F2%29%5E2
Center at (1/2,2)
r = 1/2
==============
Tangent to the y-axis at (0,2)
No x-intercept
