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?

**MathMate**, Sunday, September 27, 2009 at 10:43amYou're close.

I get

y=(1/8)x-50/8, or y=(1/8)x - 25/4

you probably had the sign reversed.

To plot the graph, you already have one point: the y-intercept, i.e. (0, -25/4).

You can get the x-intercept by substituting y=0, and solving for x.

0=(1/8)x-25/4.

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.
