To solve this worksheet, students should understand if a point is reflecting over the x-axis then the reflection rule is (x,y)→(x,-y), and if a point is reflecting over the y-axis then the reflection rule is (x,y)→(-x,y). For example, if point A(1,2) is reflected to point B(1,-2), then the axis of reflection is the x-axis because the sign of the y-coordinate is changed.
