The given expression is:

2x - y - 1 = 0

This can be written as: y = 2x - 1

Here we observe that this is a linear equation in x and y. To graph this on the number line we plug in different values for x and then calculate it for y.

Lets start plugging in values for x, say like x = 0, 1, 2, 3, 4, 5, and also -1, -2, -3, -4, -5

So the corresponding values of y will be:

x y

0 -1

1 1

2 3

3 5

4 7

5 9

-1 -3

-2 -5

-3 -7

-4 -9

-5 -11
The graph of the above table looks as follows.

Hence the solution.

Regards,
happy calculating!!
