Answer :
In your question that ask what is the slope of the linear equations that is given on you table that represents the boiling point of a water . To get or to calculate the X and Y or to formula on getting the slope of the linear equation by using the X ang Y. So the slope is -1.8
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
-1.8 units.
