as a submarine descends into the deep ocean, the pressure it must withstand increases. At an altitude of - 700 metres, the press
ure is 50 atm, and an altitude of -900 meters, the pressure is 70 atm. For every 10 meters the submarine descends, the pressure it faces increases by n, where n is a constant. What is the value of n
Answer: If a linear system has no solution, the two lines are parallel. If it has one solution, the lines will intersect at exactly one point because they have different slopes.
