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.
