/
2
feet below the

a. Use the number line and mark these two depths.
b. Write an inequality that
compares the depths of the two
fish.
c. Find the absolute value of both
depths and determine which fish
is at the shallowest level.
Explain what this means.
d. Once, farther out in the lake,
Peter saw a trout leap out of the
water! He estimated that the fish
leaped 3
1
/
