How do you solve this equation?

What is the equation of the linear function represented by the table?

Identify reflection rule on a coordinate plane that verifies that triangle a(-1,7), b(6,5), c(-2,2) and a’(-1,-7), b(6,-5), c’(-2,2) triangle are congruent when reflected over the x-axis

Need me know if option a,b,c are wrong so ik its d
