Answer:

- The graphed is attached.

- It's an enlargement.

Explanation:

A Dilation is defined as a transformation in which the image and the pre-image have the same shape, but their sizes are different.

When the scale factor is greater than 1, the image obtained after the dilation is greater than the pre-image and it is an "Enlargement".

When the scale factor is is between 0 and 1, the image obtained after the dilation is smaller than the pre-image and it is an "Reduction".

In this case we know that the scale factor is 4.

Since:


4>1

So it is an Enlargement.

Now we need to multiply the coordinates of the vertices of VWXY by 4, in order to find the coordinates of the vertices of V'W'X'Y'. These are:


V'=(-1*4,-1*4)=(-4,-4)\\\\W'(-1*4,2*4)=(-4,8)\\\\X'(2*4,-1*4)=(8,-4)\\\\Y'=(2*4,2*4)=(8,8)

Now we must draw the pre-image and the pre-image and label them, as you see in the picture attached.
