Question

A graph with a grid displays a straight line. The line begins at approximately (0, 30) on the coordinate plane and extends upward and to the right. The line's upward trajectory indicates a positive correlation. The x-axis ranges from 0 to 20, and the y-axis ranges from 0 to 120. The scale on both axes is consistent and increments are marked by every 10th value (or 20th, depending on the crop). The line appears to have a positive slope, suggesting a linear relationship.

The graph shows the amount that Miracle Maid Service charges to clean a house. They charge a flat house visit fee plus an additional cost per room to clean a house. How much is the initial house visit fee?
Responses
A $10
B $20
C $30
D $4

Answer 1

To determine the initial house visit fee from the described graph, we can focus on the starting point of the line. Since the line begins at approximately (0, 30), this indicates that when there are 0 rooms to clean (x = 0), the corresponding charge (y) is $30.

Thus, the initial house visit fee charged by Miracle Maid Service is **$30**.

The correct response is:
C. $30
