I will do Point A carefully, The others I will indicate. Start with the Given Point A. Then do the translations

A(-1,2) Original Point

Reflection: about x axis:x stays the same; y becomes -y:Result(-1,-2)

T<-3,4>: x goes three left, y goes 4 up (-1 - 3, -2 + 4): Result(-4,2)

R90 CCW: Point (x,y) becomes (-y , x ) So (-4,2) becomes(-2, - 4): Result (-2, - 4)

B(4,2) Original Point

  • Reflection: (4, - 2)
  • T< (-3,4): (4-3,-2 + 4): (1 , 2)
  • R90 CCW: (-y,x) = (-2 , 1)

C(4, -5) Original Point

  • Reflection (4,5)
  • T<-3,4): (4 - 3, 5 + 4): (1,9)
  • R90, CCW (-9 , 1)

D(-1 , -5) Original Point

  • Reflection (-1,5)
  • T(<-3,4): (-1 - 3, 5 + 4): (-4,9)
  • R90, CCW ( - 9, - 4)

Note: CCW means Counter Clockwise

The graph on the left is the same one you have been given.

The graph on the right is the same figure after all the transformations
