Check what you remember
Read the wording for your board, then hide it and explain linear modelling in your own words. Rough notes are fine. This is a self-check, with no mark or grade.
Reference: WJEC
Using straight line models in a variety of contexts, where a dependent variable changes at a constant rate with respect to an independent variable.
In context you find a gradient as a rate, such as cost per unit, then use the line to predict and interpret intercepts.
