What are the coordinates of vertex J of the pre-image? (0, -4) (0, -1) (0, 0) (0, 4)

(0,-4)

Step-by-step explanation:

The complete question is

Quadrilateral JKLM was dilated according to the rule    

DO,1/2 (x,y)( 1/2x1/2y) to create the image quadrilateral J'K'L'M', which is shown on the graph.

What are the coordinates of vertex J of the pre-image?

The picture in the attached figure

we know that

The rule of the dilation is

(x,y) -----> (1/2x,1/2y)

The coordinates of vertex J' are (0,-2) ----> see the graph

therefore

The x-coordinate of J (pre-image) multiplied by 1/2 must be equal to the x-coordinate of J' (image)

----->

The y-coordinate of J (pre-image) multiplied by 1/2 must be equal to the y-coordinate of J' (image)

----->

therefore

The coordinates of J are (0,-4)

option a is correct.

step-by-step explanation:

scale factor: it is used to find proportional measurements.

proportions means having the same ratio.

scale factor is the ratio of the model measurement to the actual measurement in a simplest form.

or we can say that the ratio of any two corresponding lengths in two similar geometric figures

if the scale factor is more than 1, then it is an enlargement,

if the scale factor less than 1, then it is a reduction.

given the two geometric figure:

by definition of proportions, we have

i would say true? if the unit was informational and it "refreshed your understanding", then true.
