Answer:

x+(-2), y+(-3)

Step-by-step explanation:

Trapezoid ABCD has vertices A(-5,2), B(-3,4), C(-2,4) and D(-1,2).

The reflection across the y-axis has the rule

(x,y)→(-x,y),

so

  • A(-5,2)→A'(5,2)
  • B(-3,4)→B'(3,4)
  • C(-2,4)→C'(2,4)
  • D(-1,2)→D'(1,2)

The translation that maps points A', B', C' and D' to E, H, G, F is

  • A'(5,2)→E(3,-1)
  • B'(3,4)→H(1,1)
  • C'(2,4)→G(0,1)
  • D'(1,2)→F(-1,-1)

and has a rule

(x,y)→(x-2,y-3)
