16) In order to calculate a reflection over the x-axis, we just need to change the signal of the y-coordinates.
So we have that:
[tex]\begin{gathered} A(-2,1)\to A^{\prime}(-2,-1) \\ B(2,3)\to B^{\prime}(2,-3)_{} \\ C(5,2)\to C(5,-2) \end{gathered}[/tex]
17) In order to calculate a reflection over the y-axis, we just need to change the signal of the x-coordinates.
So we have that:
[tex]\begin{gathered} R(0,-1)\to R^{\prime}(0,-1) \\ S(2,2)\to S^{\prime}(-2,2) \\ T(3,0)\to T^{\prime}(-3,0) \end{gathered}[/tex]
