As it is in the y=mx+b format, b, y intercept is -4.
Plot (0, -4)
...
X intercept is where y = 0
2x - 4 = 0
2x = 4
x = 4/2 = 2
Plot (2, 0)
...
Draw a line through these intercept points

It might be easier to re-write this as 2x-y=4.
Next, the x-intercept is where y=0, so 2x=4 and x=2: (2,0)
The y-intercept is where x=0, so -y=4, which means that y=-4: (0,-4)
Graph these two points, and it should look like this:
I have a LOT of explanations, examples, and FULL COLOR solutions to problems like this on my own website. I even have VIDEOS of me teaching GRAPHING of straight lines (in my younger days before I retired and my hair was still dark)!! This is a GREAT chapter if you get a good explanation of it--not nearly as hard as your textbook is making it.
My website is all FREE with NO ADVERTISING, and I'm not selling anything! I just want to make this as easy as I can for you.
To see my website go to www.mathinlivingcolor.com, named after my theme "Math in Living Color." Look for a single link near the bottom of this page that will take you to my Homepage. Once on my Homepage, look for "Basic, Intermediate and College Algebra: One Step at a Time", and select "Basic Algebra". Look in "Chapter 4" for the appropriate topics!
As for the videos, look for the link on my Homepage called "Rapalje Videos in Living Color", and choose Basic Algebra. Choose the video called "Graphing and Slope of a Line.
If you have questions on other topics, just send me an Email! I'll be glad to help you find the right page on my website. I hope you like my website and that you will recommend it to family and friends! Remember, my goal is to make math EASIER than your own textbook is making it, and it's ALL FREE!!!

The way to find intercepts is:
x-intercept:
Set y = 0 and solve for x
---------------------
y-intercept:
Set x = 0 and solve for y
---------------------
x-intercept:
Set y = 0
---------------------
y-intercept:
Set x = 0
--------------
So, now you have 2 points you can plot:
(2,0) and (0,-4)
Here's the plot:
