This lesson introduces you to the concept of finding the equation of a line rather than graphing a line. Basiclly you will be given information about a line- for example the slope or a few points that are on the line then you will have to find the y = mx + b equation for the line. Make sure you know the previous lessons well and you can solve equations. As your teacher I want you to take the time to really learn the material so don’t rush the lesson.
Things to focus on in this lesson:
• the information you need to find the equation of a line
• y = mx + b format
• how to check if a point is on a line
Chapter 6 Lesson 6
Finding The Equation Of A Line y=mx + b Method
pop quiz: slope = rise / run ?
|Wow! you are learning a ton- nice work. At this point in the course you should be able to:
* work with fractions and real numbers
* solve equations
* graph lines
Ok there are more lessons on how to find the equation of a line let’s check out the point-slope formula
