In this lesson, you will learn how to find the slope of a line given two points. By labeling the coordinates as x1, x2, y1, and y2, you can easily subtract them in the correct order to get the change in y over the change in x. Using the formula y2-y1/x2-x1, you can determine the slope of the line. Don't make the mistake of subtracting a negative number from a positive number, as this will lead to an incorrect answer.
Given two points find the slope of the line
I show how to solve math problems online during live instruction in class. This is my way of providing free tutoring for the students in my class and for students anywhere in the world. Every video is a short clip that shows exactly how to solve math problems step by step. The problems are done in real time and in front of a regular classroom. These videos are intended to help you learn how to solve math problems, review how to solve a math problems, study for a test, or finish your homework. I post all of my videos on YouTube, but if you are looking for other ways to interact with me and my videos you can follow me on the following pages through My Blog, Twitter, or Facebook.
Questions answered by this video:
