Triangle ABC has vertices at A(1, 2), B(4, 6), C(4, 2) in the coordinate plane. The triangle will be reflected over the x-axis, then rotated 180 degrees about the origin, and dilated at the origin by scale factor of 3 to form triangle A'B'C'. What are the vertices of triangle A'B'C'? Answers-
A'(3, -6). B'(12, -18), C'(12, -6)

A'(-3, -6). B'(-12, -18), C'(-12, -6)

A'(-3, 6). B'(-12, 18), C'(-12, 6)

A'(3, 6). B'(12, 18), C'(12, 6)
