Question 198184
The boiling point of water at sea level is 100 degrees celsius.  The boiling point decreases 3.5 degrees for every 1 kilometer increase in altitude.  
          a. Determine a linear function that will give the boiling point of water as a function of altitude.
{{{f(x)=100-3.5x}}}
          b. Graph the function on the axis provided. 
{{{ graph( 300, 200, 0, 30, 0, 100, 100-3.5x) }}}
          c. Use this model to determine the boiling point of water at Colorado Springs, Colorado 2 kilometers above sea level. Plot and label.
93 deg
          d. Determine the altitude(in kilometers) at which water will boil at 50 degrees celsius(round to two places)
14.29km
