Linear Functions

Linear Functions
There are three different ways to write linear functions. They are slope-intercept, point-slope, and standard form. There are certain situations where it is better to use one way than another to solve a problem. It is important to understand and comprehend the mechanics of these three forms so that you know what form to use when solving a problem.
The first form, point-slope, is written as y-y1=m(x-x1). M is the slope and x1 and y1 correspond to a point on the line. It's good to use this form when you know the slope of a line and one point on it. In order to solve a probl…
