Question

What are the coordinates of its image, J'KL, if this

Answer 1

Answer:

$J'(-15,10)\\\\K'(15,10)\\\\L'(0,-20)$

Step-by-step explanation:

For this exercise you must remember that the original figure (before a transformation) is called "Pre-Image" and the one obtained after the transformation is called "Image".

 Dilation is defined as a transformation in which the Image and the Pre-Image have the same shape, but different sizes.

If a figure is dilated by a scale factor "k" with respect to the origin, the rule is:

$(x,y)$ → $(kx,ky)$

In this case, the vertices of the triangle JKL (the Pre-Image) are:

$J(-3.2)\\\\K(3,2)\\\\L(0,-4)$

Knowing that the scale factor is:

$k=5$

You get that the vertices of the triangle J'K'L' (Image), are:

$J'=(5(-3),5(2))=(-15,10)\\\\K'=(5(3),5(2))=(15,10)\\\\L'=(5(0),5(-4))=(0,-20)$
