Answer:
y = - 400 + 700x
Step-by-step explanation:
Nour's altitude increased at a constant rate from the Dead Sea up to Amman.
Initially, her altitude was 400 meters below from the sea level and then she arrived at an altitude was 1000 meters above sea level arrived to Amman, 2 hours later.  
So, she moves (400 + 1000) = 1400 meters in 2 hours.
Therefore, her rate of change of altitude is  meters per hour.
 meters per hour.
Therefore, if y represents Nour's altitude in meters relative to the sea level after x hours then the relationship between the altitude and number of hours is given by  
y = - 400 + 700x  (Answer)
