1.
2.
tables and graphs can both show relationships between variables. data from a table are often displayed using a graph to visually represent the relationship.

Explanation:

1. For the first graph:

• The variables are "Total Cost" and "Number of Pounds".
• As the number of pounds increases, the total cost also increases. The rate of increase might change at some point (since the graph is not a straight - line throughout).
