    Triangle abc has coordinates a(-1,3), b(-6,5), and c(-4,7):
    1- The coordinates of triangle a'b'c', the image of triangle abc after a reflection in the x-axis are a'------, ----- b'-----, ----- c'-----, -----?
    2- The coordinates of triangle a''b''c'', the image of triangle abc after a reflection in the line y=x, are a''-----, ----- b''-----, ----- c''----, -----?
    3- The coordinates of triangle a'''b'''c''', the image of triangle abc under the translation which maps (x,y) to (x+8,y+3) are, a'''----, ---- b'''----,---- c'''-----,-----?
