Draw the graphs of the following straight-lines:

3y = 1.

3y =1.

For different values of X and Y

Plotting above values in the graph, we get

General equation for line is ay = bx +c

Here the line is, 3y=0x+ 1

Since ‘x’ is multiplied by zero every time, the value of ‘x’ does not affect the value of y or the equation.

⇒ For every value of x, the value of y will be constant, i.e.
