1) Write a translation rule that maps point D(7, –3) onto point D'(2, 5).

2) Triangle ABC has coordinates A(1, 4); B(3, –2); and C(4, 2). Find the coordinates of the image A'B'C' after a reflection over the x-axis.

1. Does (x,y) ---> (x-5, y+8 ) work ?

2. the x's would stay the same, the y's would got to their opposites
e.g. A(1,4) ---> A'(1,-4)
etc
