Final answer:
Economists use graphs to illustrate abstract relationships between variables in economics.
Step-by-step explanation:
Economists make extensive use of graphs because they are interested in abstract relationships between X's and Y's. This statement is true. Graphs, such as line graphs, are widely used in economics to visually illustrate the relationship between two variables that are both changing. Line graphs can show patterns, trends, and comparisons over time, providing an intuitive sense of relationships in the data. For example, economists often use line graphs to depict the relationship between quantities bought and sold or the size of the economy.
