Linear relationships
Graphs for linear relationships appear as straight lines, either sloping upwards, downwards, or horizontal. The equation for a linear relationship is typically in the form y = mx + b, where m represents the slope and b represents the y-intercept. In tables for linear relationships, the values of y change at a constant rate for each unit change in x.
Examples of linear relationships:
A print shop charges a flat fee for printing documents plus a per-page cost.Suppose the print shop charges 2 for the service. The equation representing this linear relationship would be:
- y as the total cost of printing.
- 𝑥 as the number of pages to be printed.
- 𝑚 as the cost per page.
- 𝑏 as the flat fee (y-intercept).
