Question

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

1/2

Answer 2

thank you (:

Answer 3

since the change in each one is .5, because you just keep adding .5, in a fraction, it is 1/2 and its better to have slope as a fraction

Answer 4

^no

Answer 5

Slope is change in y divided by change in x
\[m=\frac{ y_2-y_1 }{ x_2-x_1 }=\frac{211.1-212.0}{0.5-0}\]

Answer 6

or change in boiling point per change in altitude for this application.
And you can use any two points to do this. I used the first two points
