Answer:
[tex]J'(-15,10)\\\\K'(15,10)\\\\L'(0,-20)[/tex]
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:
[tex](x,y)[/tex] → [tex](kx,ky)[/tex]
In this case, the vertices of the triangle JKL (the Pre-Image) are:
[tex]J(-3.2)\\\\K(3,2)\\\\L(0,-4)[/tex]
Knowing that the scale factor is:
[tex]k=5[/tex]
You get that the vertices of the triangle J'K'L' (Image), are:
[tex]J'=(5(-3),5(2))=(-15,10)\\\\K'=(5(3),5(2))=(15,10)\\\\L'=(5(0),5(-4))=(0,-20)[/tex]
