The circle equation is $\"\"$ .

$\"\"$

Compare the equation with the standard form of circle : $\"image\"$ .

Center $\"\"$ and radius $\"\"$ .

$\"\"$

Center at $\"\"$ and radius is 1 unit.

Plot the points :

Up : $\"\"$

Down : $\"\"$

Left : $\"\"$ , and

Right : $\"\"$ . $\"\"$

1. Draw the co-ordinate plane.

2. Plot the center at $\"\"$ .

3. Plot 4 points " radius away from the center in the up, down, left and right direction.

4. Sketch the circle.
