Use the two-point form of an equation of a line:

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.)
