Question

For problems 16-17, graph and reflect the figure with the given vertices across the given line.16) A(-2, 1), B(2, 3), C(5, 2); x-axis17) R(0, -1), S(2, 2), T(3, 0); y-axis

Answer 1

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:

`\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}`

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:

`\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}`
