Given: The square STUV
To Determine: The coordinate of the image after reflection over the y-axis
Solution
The reflection over the y-axis rule is
[tex](x,y)\rightarrow(-x,y)[/tex]Locate the coordinates of STUV
Let us apply the rule to get the coordinate of the image
[tex]\begin{gathered} S(-10,-10)\rightarrow S^{\prime}(10,-10) \\ T(0,-10)\rightarrow T^{\prime}(0,-10) \\ U(0,0)\rightarrow U^{\prime}(0,0) \\ V(-10,0)\rightarrow V^{\prime}(10,0) \end{gathered}[/tex]Hence, the coordinate of the image after a reflection over the y-axis is
S'(10, - 10)
T'(0, - 10)
U'(0, 0)
V'(10, 0)
