Question

Type the correct answer in the box. Use numerals instead of words. If necessary, use / for the fraction bar.

The table gives the boiling point of water at different altitudes.

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
Based on the table, the linear equation that represents the change in water’s boiling point for every 1,000-foot change in altitude has a slope of
units.

Answer 1

Answer:

Explanation:

Identify the changes (Δ) in each consecutive pair of x-values and y-values, then calculate the corresponding values of Δy/Δx

Your working table should look like the one below.

Answer 2

`\large \boxed{\text{-1.8$^(\circ)$F/1000 ft}}`

Explanation:

Identify the changes (Δ) in each consecutive pair of x-values and y-values, then calculate the corresponding values of Δy/Δx

Your working table should look like the one below.

`\begin{array}{cccc}\textbf{Alt/1000 ft} & \textbf{B.p.$/^(\circ)$F} & \Delta\textbf{B. p}& \Delta\textbf{B.p/1000 ft}\\0 & 212.0 & & \\& &-0.9 & -1.8\\0.5 & 211.1 & & \\& &-0.9 & -1.8\\1.0 & 210.2 & & \\& &-1.8 & -1.8\\2.0 & 208.4 & & \\& &-1.8 & -1.8\\3.0 & 206.6 & & \\& &-1.8 & -1.8\\4.0 & 204.8 & & \\& &-0.9 & -1.8\\4.5 & 203.9 & & \\\end{array}`

`\text{ The change in boiling point per thousand feet of altitude is $\large \boxed{\textbf{-1.8$^(\circ)$F/1000 ft}}$}`
