Do the graphs below show interpolation or extrapolation?

Do the graphs below show interpolation or extrapolation?Interpolation

A faster rate of change is indicated on a line graph where the slope of the line is ________.

A faster rate of change is indicated on a line graph where the slope of the line is steeper.

Segment A

Segment B

Segment C

Segment A of the graph has the steepest slope, therefore this is when the rate of temperature change is the greatest.

Segment C has the lowest slope, therefore here temperature is changing the slowest.

Notice that while the temperature is always increasing with greater depth, the rate of change is not steady. This means that the rate of change is not the same everywhere on the line. We know this because we can see that the slope of the line is not the same everywhere.
