In a graph with several intervals o data how does a constant interval appear? what type of scenario produces a constant interval?

A horizontal line; a melting ice cube.

Step-by-step explanation:

A constant interval appears as a horizontal line. The graph in the interval has a slope m = 0.

Here's an example of a constant interval.

You take an ice cube from the freezer and place it in a container on the counter.

The temperature of the ice cube is -5 °C. The ice cube will warm to 0 °C, and then it will start to melt. While it is melting, the temperature is constant at 0 °C.

When the ice has completely melted, the water will start warming to room temperature.

A plot of temperature vs. time would look something like the graph below.

The interval AB, where the ice is melting, is a constant interval.

T=4(P+0.25)

Step-by-step explanation:

The total cost of the bus fare for Paul and Jonas equals the cost of two bus tickets to the fair and back. (two bus tickets each way equals four one-way tickets)
