Center is (0,0)   Radius = 3/4
 (h,k) is the coordinates of the center of the circle

(x-h)² + (y-k)² = r²

substituting, we have:
(x - 0)² + (y-0)² = (3/4)²
x² + y² = 9/16

Transform or re-write the equation to general forn:
ax² + by² + c = 0

x² + y² - 9/16 = 0

To sketch/graph:

1.  Start from the center (0,0) which is also the intersection of axes x and y.
2.  Slide your pencil to the right/left/up/down by radius 3/4 of a unit.
