Question 1069842: A Submarine that is 7500 meters below sea level surfaces at a rate of 80 meters per minute . The depth of the submarine after m minutes is given by d(m)=-7500+80m


Make a table and graph of this function.

Here's a graph:
+graph%28+600%2C+600%2C+-200%2C+200%2C+-12000%2C+4000%2C+80x+-+7500+%29+
+d%28m%29+=+-7500+%2B+80m+
The graph is easy to make
Pick a value for +m+, like m = 0, 10, 20, 30, 40, 50, etc
Find +d%28m%29+ for each pick
For instance:
+m+=+50+
+d%2850%29+=+-7500+%2B+80%2A50+
+d%2850%29+=+-7500+%2B+4000+
+d%2850%29+=+-3500+
--------------------
Note that +d%28m%29+=+0+ gives me
+0+=+-7500+%2B+80m+
+80m+=+7500+
+m+=+93.75+
This is +m+ for sea level
Any value of +m+ greater than +93.75+
and likewise, any +d%28m%29+ greater than +0+ is
meaningless since a submarine can't fly
