It's been a while since I've done algebra, but that's in y-intercept form, isn't it (also called slope-intercept)??
, where is your slope, and is the y-intercept (that is, where the line crosses the y-axis).
So in your equation, the slope is (or , same thing, just remember ) and the y-intercept is .
Also, I attached a graph with my notes in red. Does this help at all, or did I not understand your question?
