The slope intercept form is always



Well, what about something like



you ask. Well remember that is really .

If you remember it this way, you will seldom, if ever, get confused about signs.

The -intercept is at the point , so if you are given the point then . You are also given that , so just replace the values.



The standard form is



So, multiply both sides of your equation by 4 (remembering to multiply BOTH terms of the RHS) and then add to both sides. Done.
