The temperature at which water starts to boil is also linearly related to barometric pressure. water boils at 212 degrees f at a pressure of 29.9 inhg (inches of mercury) and at 191 degrees f at a pressure of 28.4 inhg.
a) find a relationship of the form t=mx+b, where t is degrees f and x is pressure in inches of mercury
b) find the boiling point at a pressure of 31 in hg
c) find the pressure if the boiling point is 199 degrees f
d) graph t and illustrate the answers to (b) and (c) on the graph
