Question: Write the point-slope form of the lines equation satisfying the condition. Then use the point slope form of the equation to write the the slope intercept form of the equation in function notation.
Passing through (-4,5) with y-intercept=-3
-------------------------------------
The clue here is to interpret:

"with y-intercept=-3"

as

"and passing through (0,-3)"

Now that you have two points, you can determine the slope.  Once you have that, you just:

1. write the basic point-slope form.
2. substitute your m and a point (either one).
3. do the algebra necessary to reduce it to  "y = ...."

and you are done.  If you get stuck, send me what you did and I'll try to help.
