A scuba diver standing on a boat is at an altitude of 1.3

meters above sea level. The scuba diver jumps into the water and decreases his altitude by 5.6 meters in one minute.

​

​Which equation can be used to determine the scuba diver's altitude, in meters relative to sea level, one minute after jumping into the water?

• 1.3+5.6=6.9

• −1.3+5.6=4.3

• 1.3+(−5.6)=−4.3

• −1.3+(−5.6)=−6.9
