Question

Help me I beg u! The pre-image coordinates of a triangle are J(-6,9), K(-6,4), and L(-3,4). The coordinates of the transformed triangle are J'(2,9), K'(2,4), and L'(5,4). What transformation has occurred? A. translation B. reflection C. dilation D. rotation Reset Next Question

Answer 1

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
