Draw the graph of the following equations:

y = 0

y = 0 means the y co-ordinate is fixed and we can take any value of x

to draw graph we will require two points

let us consider point P whose x co-ordinate be 2 and y co-ordinate is already given as 0

⇒ P (2, 0)

Now consider point Q whose x co-ordinate be 4 and y co-ordinate is already given as 0

⇒ Q (4, 0)

Plot points P and Q and join them to get the graph of y = 0
