Noa drove from the Dead Sea up to Jerusalem. When she arrived in Jerusalem after 1.5 hours of driving her altitude was 710 meters above sea level. Her altitude increased at a constant rate of 740 meters per hour. Let y represent Noa’s altitude (in meters) relative to sea level after x hours Complete the equation for the relationship between the altitude and the number of hours.
Y=
