A certain mountain has an elevation of 19,762 feet. In 1908, the glacier on this peak covered 5 acres. By 2000 this glacier had melted to only 1 acre. Assume that this glacier melted at a constant rate each year. Find the yearly rate.

I also need to find out how to write a linear equation that gives the acreage.

## Comments

looks like the equation should be: y = -0.043x + 5
