The table gives the boiling point of water at different altitudes.
2 answers:
We will use the points (2 , 208.4) and (1 , 210.2) to find the slope of the line.
m = (210.2 - 208.4) / (1 - 2)
m = -1.8
The boiling point of water decreases by 1.8 °F for every 1000-foot increase in altitude.
Answer:
1.8
Step-by-step explanation:
Altitude (1,000 feet) Boiling Point of Water (°F)
0 212.0
0.5 211.1
1.0 210.2
2.0 208.4
2.5 207.5
3.0 206.6
4.0 204.8
4.5 203.9
Formula of slope m =
Substituting the values in the formula
Hence the linear equation that represents the change in water’s boiling point for every 1,000-foot change in altitude has a slope of 1.8 units.
