In this video, we look at how to find the equation of a line when given a pair of coordinates.
I start by using the gradient formula to find the gradient before using 2 methods to then find the equation of the line. See which method you might like best.
Before watching this video, you really should check out the first video I did on the equation of a line:    • Learn how to find the equation of a s...  
There is a surprise video at the end.
