Step 1: Note down the given  circle equation

EXAMPLE: (x -2)^2 + (y + 1)^2 = \frac{169}{4}

Step 2: Convert the given equation in to standard form

NOTE: Make sure the terms with x^2 and y^2 are on

the left side of the equation and the constant is on the right.

EXAMPLE: $(x-2)^2+\left[y-\left(-1\right)\right]^2=\frac{169}{4}$

Step 2: Compare the given equation with the Standard form of circle.

EXAMPLE: $(x-2)^2+\left[y-\left(-1\right)\right]^2=\frac{169}{4}$  Compare it with

(x - h)^2 + (y - k)^2 = r^2

Where center  (h, k) and radius r

Step 3: Identify the r, h and k values.

h is x-coordinate

k is y- coordinate of the center.

EXAMPLE; (h, k) = (2, -1), r = \frac{168}{4}

Step 4: Plot the center on the graph

NOTE: Represent the points on the graph sheet

Step 5: Take the length of the radius and draw a circle

NOTE: Use the compass to draw a circle in the graph sheet.
