my question is
"Graph the equation. If necessary, write the equation in slope-intercept form first."
11) y = 1/2x - 4

it's not the graphing part I'm TOO worried about. It's just the other part of it. I know how to find slope very well.
Would the answer be something like this??
M=1/2
b=0
then I would graph it?
