Thread: Y-intercept form

AAAAAA!!!!! I havnt done homework in a long time, and i just got sent home a take-home test on y-intercept form. An explanation would be nice, as well as answering this purely example question:

y = 2x + 4

just convert it into y-intercept, i learn by example.

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?
