Question

A group of researchers are working to determine the historic sea levels of the body of water. They are attempting to do this by taking samples around the body of water and in a nearby cave and after analyzing sediment cores from around the body of water to those in the cave.

The Climatologist that is working in the cave is trying to determine the age and growth rate of stalactites, to get a more accurate picture of the age of the existing stalactites. The following table contains the estimated age (to the nearest hundred) of the sample and the length of the sample in centimeters. Find a linear model that express length as a function of the age.

Round your answers to 2 decimal places

Length = __________________x+__________________ where x is the age in hundreds of years

Age (nearest hundred)   Centimeters
2   163.96
3   245.75
6   492.37
14   1147.14
18   1476.74
19   1557.22
20   1638.36
