Question 89039: what are the steps for graphing 2x-y=1=0
Answer by chitra(359)  (Show Source):
You can put this solution on YOUR website! 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!!
