Final answer:
The graph represents a linear relationship between the number of fidgets Diego buys and the amount of money Diego has after buying the fidgets.
Step-by-step explanation:
The subject of this question is Mathematics and the grade level is High School.
The graph represents a linear relationship between the number of fidgets Diego buys and the amount of money Diego has after buying the fidgets. In other words, as the number of fidgets increases, the amount of money he has decreases. This relationship can be represented by the equation y = mx + b, where y is the amount of money, x is the number of fidgets, m is the slope of the line, and b is the y-intercept.
For example, if Diego buys 0 fidgets, the equation becomes y = m(0) + b, which simplifies to y = b. This means that Diego will have a certain amount of money even if he doesn't buy any fidgets. On the other hand, if Diego buys a certain number of fidgets, the equation becomes y = mx + b, which means that the amount of money he has will decrease as the number of fidgets increases.
