You can create a table by substituting any value for x and then solving for y. I'll be taking 3 values:

  1. Let x=0
    Then,
    y=2(0)−1
    y=−1
  2. Let x=1
    Then,
    y=2(1)−1=2−1
    y=1
  3. Let x=2
    Then,
    y=2(2)−1=4−1
    y=3

We can then make a table for x and corresponding y values as follows:

x⋆⋅(0)⋆⋅(1)⋆⋅(2)
y⋆⋅(−1)⋆⋅(1)⋆⋅(3)

So, you'll get three points on the graph with x-coordinates and y-coordinates that can be taken from the table as (0,−1),(1,1)and(2,3)

Plot the points, and pass a straight line through them. The graph will look something like this:
