4. Choose the slant of the constant rate of change for the graph below.

[Graph of a horizontal line at y = -3]

• negative
• positive
• zero
• undefined

Solution

The graph shows a horizontal line at \( y = -4 \). A horizontal line has a slope (rate of change) of zero because there is no vertical change as \( x \) changes. Therefore, the constant rate of change for the graph is: zero
