standard_description: For a function that models a relationship between two quantities, interpret key features of graphs and tables in terms of the quantities, and sketch graphs showing key features given a verbal description of the relationship. Key features include: intercepts; intervals where the function is increasing, decreasing, positive, or negative; relative maximums and minimums; symmetries; end behavior; and periodicity.
problem_activity: Problem 1
Consider the set of numbers
$$6$$
,
$${4 \frac{1}{2}}$$
,
$$2$$
, and
$$5$$
, and answer the questions that follow.

b.   Write the opposites of each number and graph them on the number line.
c.   Order the opposites from least to greatest.
d.   Is −5 greater than −2? Explain using your number line.
Problem 2
Order the rational numbers below from least to greatest.
$${5, -4, -\frac{1}{3}, \frac{10}{3}, 3, 0, -4\frac{1}{4}, -4\frac{3}{4}}$$
What strategies did you use to determine the correct order?
Problem 3
A student orders three rational numbers from least to greatest as:
$${{{{{{{{{-5}}}}}}}}}$$
,
$${{{{{{{{{-5}}}}}}}}} \frac {1}{3}$$
,
$$6$$
