standard_description: Write simple expressions that record calculations with numbers, and interpret numerical expressions without evaluating them. For example, express the calculation “add 8 and 7, then multiply by 2” as 2 × (8 + 7). Recognize that 3 × (18932 + 921) is three times as large as 18932 + 921, without having to calculate the indicated sum or product.
problem_activity: Problem 1
Point
$$Q$$
is located at
$$(-3,2)$$
. It is reflected over at least one axis and is now located at
$$(-3,-2)$$
. Describe the reflection that took place.
Problem 2
Riley reflects point
$$L$$
, located at
$$(5,4)$$
, over the
$$y$$
-axis. They determine its new location is at
$$(4,-5)$$
. Did Riley correctly identify the coordinates of the reflected point? Explain your reasoning.
