A certain mountain has an elevation of 19,338 feet. In 1921, the glacier on this peak covered 7 acres. By 2001 this glacier had melted to only 1 acre.

A) assume that this glacier melted at a constant rate each year.
B) Use youir answer for part A to write a linear equation that give the acreage A of this glaicer t years past 1921.

So far I have: m = (y-y)/ (x-x) = 7-1

(1921, 7) & (2001, 1)

Am i on the right track?
