Linear Functions and Graphs
A constant first difference corresponds to a linear relationship in equally spaced x-values.
Key ideas
- tables of values
- gradient/intercept
- graph interpretation
- model contexts
- solve intersections graphically
Formula / rule: y=mx+b.
Worked example: y=−2x+5 decreases by 2 when x increases by 1.
Common trap: A negative gradient means y decreases as x increases.
Key words
function — rule assigning outputs to inputs
gradient — constant rate of change
intercept — axis crossing
domain — allowed input values
range — resulting output values
How to use this drill: review the short notes when learning, then close them on later attempts and practise from memory. The rotating bank delays a full set repeat for 30 attempts on the same browser.
