To solve this worksheet students should have a good understanding of reflection and coordinate plane. 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).
It means if a point is reflected over both axes then the rule of reflection is (x,y)→(-x,-y). For example, if the point (1,7) is reflected over the x-axis followed by reflected over the y-axis, then the coordinates of the new point after reflection are (-1,-7).
