A math tutoring company sells cards that teach different properties of equations. The relationship between number of cards and total number of equations presented is represented by the graph shown below.

Question



Use the drop-down menus to choose the responses that best completes each sentence below.

On the graph of any proportional relationship, the y-intercept is represented by the point Query 1.

On this graph, the y-intercept represents Query 2.

On this graph, the unit rate is Query 3.

The unit rate indicates the Query 4.

Answer 1

To complete the sentences about the graph of a proportional relationship, we can use the following responses for the dropdown menus:

1. On the graph of any proportional relationship, the y-intercept is represented by the point (0, 0).

2. On this graph, the y-intercept represents the situation where no cards are sold, and therefore no equations are presented.

3. On this graph, the unit rate is the slope of the line, indicating how many equations are taught per card.

4. The unit rate indicates the rate at which the total number of equations increases as more cards are sold.

Feel free to adjust the responses based on the specifics of the graph you are looking at!
