Exercise 10 Page 51

We can use a number line to help us determine which symbol should be used to complete the statement. Let's start by graphing $\text{-}7$ and $\text{-}13$ on a number line.

Numbers that lie further to the left on a number line are smaller, while numbers that lie toward the right are bigger. Since $\text{-}13$ lies to the left of $\text{-}7,$ we can conclude that $\text{-}7$ is greater than $\text{-}13.$
