Answer:
Option B is correct.
The reflection rule is followed here is, [tex](x,y) \rightarrow (x, -y)[/tex].
Explanation:
Since, the triangle is reflected over the x-axis , then only y- coordinates will get changed but the x coordinates will remain the same.
[tex]A(-1,7) \rightarrow A'(-1,-7)[/tex]
[tex]B(6,5) \rightarrow B'(6,-5)[/tex]
[tex]C(-2,2) \rightarrow C'(-2,-2)[/tex]
Therefore, the only reflection rule on the coordinate plane that verifies the triangle are congruent when reflected over x-axis is, [tex](x,y) \rightarrow (x, -y)[/tex]
