Since \ =\ -3)
, you know that when 
, the value of the function is -3, which is to say 
. Hence, the point )
is on the graph of your function. Similarly, the point )
is also on the graph of your function. Use the two-point form of an equation of a straight line (straight line because you are trying to derive a linear function), to derive an equation of the line.
(x\ -\ x_1) )
where )
and )
are the coordinates of the given points.
Plug in your values, simplify and then replace 
with )
or )
or )
or TheArtistThatWasFormerlyKnownAsPrince(x)...you get the idea.
