# Linear functions and graphs, including gradient resources

### Quick Reference (2)

Linear relationships

In many business applications, two quantities are related linearly. This means a graph of their relationship forms a straight line. This leaflet discusses one form of the mathematical equation which describes linear relationships.

The slope-intercept form

This leaflet explains the slope-intercept form of an equation describing a straight-line.

### Teach Yourself (1)

Linear functions

Some of the most important functions are linear. This unit describes how to
recognize a linear function, and how to find the slope and the y-intercept
of its graph.
