Ok, I'm new to this and dont know how to graph on this site so i'll explain it to you.
First, you need to move this equation around to the y=mx+b equation format
y is the number that is in front of it in the equation, same with x too
The b is the number without a variable
In y=mx+b form this equation would be 4y=x+8 by moving the x to the other side by subtraction
To graph, you need y to be single so divide all the numbers by four to get it by itself, y=1/4+2
Now to graphing it, first you have to graph the yintercept or veritcal line which is 2, so graph 2 on the vertical line
Then you can finish this graph two ways, first you have to know rise over run and that is 1/4, this can be portrayed as 1/4 or 1/4
So for rise you could negative one, which move down one space from the 2 or yintercept and go positive 4, which is to the right, you could also do positive rise one which is up, and negative run 4, to the left from the yintercept,make sure you have at least three points in your graph
