Graphthe equation y plus 6 equals 1/8(x2
1/8x  2/8
add 2/8 to 6, so 61 times 8/8 makes it 48/8 plus 2/8 is 50/8
mx plus c would be 1/8 plus 50/8. Is this correct so afr?
If so how do I graph 50/8? Do I just put at 50 on the y axis and do 1/8 rise over run?

You're close.
I get
y=(1/8)x50/8, or y=(1/8)x  25/4
you probably had the sign reversed.
To plot the graph, you already have one point: the yintercept, i.e. (0, 25/4).
You can get the xintercept by substituting y=0, and solving for x.
0=(1/8)x25/4.
In theory, two points are sufficient to plat a straight line. However, I suggest you take a third point, for example, x=20, to confirm that all three points lie on a straight line and avoid arithmetical errors.
