Mr. Mole left his burrow that lies 7 meters below the ground and started digging his way deeper into the ground, descending at a constant rate. After 6 minutes, he was 16 meters below the ground. Let A represent Mr. Mole's altitude (in meters) relative to the ground after t minutes.

Answer:
A=-1.5t-7
Step-by-step explanation:
Mr. Mole's burrow lies 7 meters underground (0,-7). This is the y-intercept.
After 6 minutes, he was 16 meters below the ground (6,-16).
m= -16-(-7) = -9/6 = -1.5
6-0
Going down at a rate of 1.5 meters per minute.
The slope is -1.5 and the y intercept is (0,-7), so the equation is A=-1.5t-7
