Answer:

A. Translation

Explanation:

Given

Preimage


J = (-6,9)


K = (-6,4)


L = (-3,4)

Image


J' = (2,9)


K' = (2,4)


L' = (5,4)

Required

Which transformation occurred

The transformation that occurs is translation because each of the preimage were translated or shifter right by 8 units.

The rule applied here is:


(x,y)=>(x+8,y)

So, we have:


J = (-6,9)
==> (-6+8,9) = (2,9)


K = (-6,4)
==> (-6+8,4) = (2,4)


L = (-3,4)
==> (-3+8,4) = (5,4)

Hence, the transformation is (a) Translation
