Equations of a line are often represented in slope-intercept form:

where

If you were **given** **two points** and asked to solve the system of equations (or find the equation of the line), then you need to __solve for m and b__.

E.g. using two points on a line: (2, 5) and (3, 7), we have

which you can solve to find

and your solution:

Hopefully that helps...it's basically a long winded way of saying what Irene, Mark & Phillip were hinting at.
