Answer:
?=38
average rate of change =3 (on the way they partitioned the x's)
Step-by-step explanation:
This is a line because it has the same rise/run (
) per pair of points.
That is, the following are equal:
The slope (also called the rate of change) is 3.
This means the calculating of the last pair of points should have the same rise/run.
That is we should have:
Multiply both sides by 4:
Add 26 on both sides:
Answer:
- temperature is decreasing as time passes
- x-axis
- hot drink temperature (°C)
Step-by-step explanation:
1. Each value of temperature is lower than the one previous, so we can say the temperature is decreasing. We also notice that the rate of decrease is getting smaller, possibly because the temperature is approaching a horizontal asymptote.
__
2. The horizontal axis, where temperature is plotted, is conventionally called the x-axis.
__
3. The label on the vertical axis is "temperature" and the graph title is "cooling a hot drink ...", so we presume the dependent variable is the temperature of a hot drink.
