Linear equations can be written in many forms. Discover how to use two coordinate points to solve for a line's slope and write an equation in slope-intercept form. With some algebraic manipulation, you will learn how to write a linear equation from slope-intercept form into standard form. All from just two points on the line.

Tutorial

In this lesson, I'll show you how to take two points on a line -- say, (5,3) and (-9,1) -- and use this information to write an equation in standard form for the line!
