## anonymous one year ago 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.

1/2

thank you (:

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

^no

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

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
