Given the points J(4,3), A(7,4) and R(5,2)
If there is a reflection image across the given line R_x= 1, the translation rule is
[tex]T(x,y)\to T(-x+2,\text{ }y)[/tex]
Then the coordinates of the image will be
[tex]\begin{gathered} J(4,3)\to J\text{'(-2,3)}_{} \\ A(7,4)\to A^{\prime}(-5,4) \\ R(5,2)\to(-3,2) \end{gathered}[/tex]
The graph of the reflection of JAR to J'A'R' across the given line x = 1 is shown below
