<PRE><B>Question 89039</B>
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.


{{{ graph( 300, 300, -15, 15, -15, 15, 2x - 1) }}} 


Hence the solution.

happy calculating!!
