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.
