The vertices of triangle ABC are A(1.1), B(1,5), and C(7.1). If triangle ABC is reflected across the x-axis to create triangle A'B'C', what would be the new coordinates for the vertices of this new triangle? А
A' (1-1), B(5-1), C (-1,-7)
B
A' (1-1), B(-1,-5), C (-7,-1)
С
A' (-1,1), B (-1,5), C (-7.1)
D
A' (1-1), B(1,5), C (7.1)
