### How to Write an Equation of a Line when given Two Points - Algebra I

In this video, you will learn how to write an equation of a line when given two points. The first step is to write out the slope intercept form of a linear equation, which is y=mx+b. Remember that you are looking for the values of m and b, m being the slope and b being the y-intercept. To find the slope, use the slope formula. To find the y-intercept, use any of the given points and substitute into the slope intercept formula with the slope. Once you have both values, simply substitute into the slope intercept form and you have your equation. For more, subscribe and don't forget to hit like and leave a comment below!
