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.
