Lesson 1:
Starter : (20 mins)
Click on the links below to find out more about Linear Law.
a) Movie on y = mx + c
b) What is a Line of Best Fit ? (Manual)
By now , you should get a pretty good idea of linear law. It is simply about non-linear functions in variables of x and y that can be reduced to linear functions in the form :
Y = mX + c
where m = gradient, c = Y -intercept and X and Y are expressions in terms of x and /or y.
