A sea lion jumped out of the water to a height of 3 feet above sea level. The number line shows the location of the sea lion at
the top of its jump. From this location, the sea lion dove down 9 feet. Describe how to use the number line to find the new location of the sea lion.
A. On the number line, move 9 units to the left. End at -6. The sea lion was 6 feet below sea level.
B. On the number line, move 9 units to the right. End at 12. The sea lion was 12 feet above sea level.
C. On the number line, move 9 units to the right. End at 6. The sea lion was 6 feet above sea level.
D. O3n the number line, move 9 units to the left. End at -12. The sea lion was 12 feet below sea level.
