Joan represents the height at which a sea gull is flying at +4 feet and the depth at which a fish is swimming at −1 feet on a number line, where 0 represents the surface of the water. Which of these explains whether the sea gull or the fish is closer to the surface of the water?
1 )The fish is closer to the surface of the water because |+4| = 4 and − |−1| = −1, and −1 < 4.
2)The sea gull is closer to the surface of the water because |+4| = −4 and |−1| = −1, and −1 > −4.
3 )The fish is closer to the surface of the water because |+4| = 4 and |−1| = 1, and 1 < 4.
4)The sea gull is closer to the surface of the water because |+4| = 4 and − |−1| = 1, and 4 > 1.
