In this lesson, we learn how to find the equation of a line given a point and a slope. The point-slope formula is used to solve this type of problem. By plugging in the given numbers, we can easily find the slope and the y-intercept, which allows us to write the equation of the line in slope-intercept form. This method is straightforward and eliminates the need to plot multiple points on the graph.
Finding the equation of a line given a point and a slope
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.
