Answer:
D: (x,y) → (x +1, y - 8)
Explanation:
The red shape, KHIJ, is similar to the blue shape, KHIJ.
Looking at the shapes from the points K, Blue K is forward on the x-axis by 1, Hence x + 1.
Lokkin at the same points, but on y-axis this time. Red K is up 2 and Blue K is down 6. 2 + 6 = 8. Since the blue shape is down, make the 8 into -8. Now you have y -8.
