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

Answer:

A. Translation

Step-by-step 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
