Answer:
- b = -0.0014a +215
- 211.36 °F
Step-by-step explanation:
We are given two points: (a, b) = (8100, 203.66) and (4700, 208.42). We can use these in the 2-point form of the equation for a line
y = (y2 -y1)/(x2 -x1)(x -x1) +y1 . . . . . . line through (x1, y1) and (x2, y2)
Using the given values, we have ...
b = (208.42 -203.66)/(4700 -8100)(a -8100) +203.66
b = 4.76/-3400(a -8100) +203.66
b = -0.0014a +215 . . . . . simplify
__
At 2600 ft, the boiling point is ...
b = -0.0014(2600) +215 = 211.36 °F
