The Maths Prof: Finding Equations of Straight Lines

In this lesson I show you how to find the equation of a straight line when you know the coordinates of two different points along that line. You can use this method when the coordinates of two points have been given to you, or, by selecting two points yourself when presented with a diagram of the graph.

**Tip** Brush up on...
...to become a real pro at finding equations! :-)

I hope that you find the lesson useful. Subscribe to my YouTube channel to stay up to date with new uploads and follow me on Instagram @themathsprof for more maths!

For the first time in my life i'm actually sitting down and learning math and actually is learning something like this is crazy!

Hello Professor, it was lovely watching you that you are making effort in the early morning were birds are singing, but i wanted you to derive the logic that to calculate slope why we take rise upon run, like you derived the reason of applying pythagorus therom while calculating distance between two points. Thanks professor.

Thanks for this video! But pls make video on equation of straight line in form of ax+by+c=0
Anyway you're video are very informative!
