A rock climber begins climbing at an altitude of 120 meters. She climbs at a rate of 50 meters per hour. Which equation can be used to find the altitude of the rock climber, y, after x hours?

y=50x+120

Step-by-step explanation:

y is the ending altitude

x is the number of hours the climber has climbed

put 50 before x because that how fast the climber is climbing

then 120 is your y intercept
