Linear Graphs
A straight-line relation has a constant gradient. In y=mx+b, m is gradient and b is the y-intercept.
Key ideas
- gradient
- y-intercept
- tables of values
- plotting lines
- linear models
Formula / rule: y = mx + b.
Worked example: y=3x+2 has gradient 3 and y-intercept 2.
Common trap: Gradient is rise/run, not run/rise.
Key words
gradient — change in y divided by change in x
intercept — where a graph crosses an axis
linear — constant rate of change
coordinate — ordered pair
equation — rule relating variables
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.
