A certain mountain has an elevation of 19,273 feet. In 1921, the glacier on this peak covered 4 acres. By 2001 this glacier had melted to only 1 acre. (a) Assume that this glacier melted at a constant rate each year. Find this yearly rate. (b) Use your answer from part (a) to write a linear equation that gives the acreage A of this glacier t years past 1921.

![A certain mountain has an elevation of 19,273 feet. In 1921, the glacier on this peak covered 4 acres. By 2001 this glacier had melted to only
1 acre.
(a) Assume that this glacier melted at a constant rate each year. Find this yearly rate.
(b) Use your answer from part (a) to write a linear equation that gives the acreage A of this glacier t years past 1921.
The yearly rate of change is
acres/year.
(Type an integer or a decimal. Round to the nearest thousandth.)
What is the equation that gives the acreage of the glacier t years after 1921?
(Simplify your answer. Type your answer in slope-intercept form. Use integers or decimals for any numbers in the equation.)](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F375a8daa-a061-40df-aa13-f324a3b06fab%2F6b3e7cea-abfd-485c-a5dd-97560c0b6ac6%2Fnhschgx_processed.png&w=3840&q=75)
