11. Use Patterns and Structure Becky draws a
triangle with vertices A(6,7), B(9,3), and m
C(4,-2) on a coordinate grid. She reflects the
triangle across the line y = 4 to get AA'B'C'.
She then reflects the image across the line
x = 3 to get AA"B"C".
a. What are the coordinates of AA'B'C' and
AA"B"C"?
b. Write a rule for each reflection.


Does anyone know how to do it?
