x 2 + y 2 = 4 is the formula for a circle with radius 2.
The center is 0,0 and you can graph it to show that center bysolving the equation for y:
y = 4 x 2
And
y = 4 x 2

It looks like a standard form
Standard form: Ax + By = C
in this case, you have x = a and b=y, leading to your weirdequation.
C/A = x-intercept = 4/x
C/B = y-intercept = 4/y
