Use the two-point form of an equation of a line:
(x\ -\ x_1) )
where )
and )
are the coordinates of the given points.
You certainly need to do any indicated arithmetic and then you may also have to simplify and/or rearrange to one of the typical forms desired, namely the slope-intercept form: 
, or the Standard Form: 
. (Note: some texts/professors require that A, B, and C be integers for proper standard form. Check before you hand in a paper.)
