Meaning
Linear refers to a straight line.
About Linearity
- A scatter graph with a straight line of best fit is referred to as a linear graph.
- A linear graph has a constant gradient.
Examples

 |
 |
| This scatter graph shows a linear relationship where x increases and y increases.
\(y = mx + c\) Where m, the gradient, is positive. |
This scatter graph shows a linear relationship where x increases and y decreases.
\(y = mx + c\) Where m, the gradient, is negative. |
This scatter graph shows a linear relationship that is directly proportional where x doubles, y doubles.
\(y = mx\) Where m, the gradient, is positive. |
