Answer: OPTION A.
Step-by-step explanation:
Dilation is defined as transformations in which the Image (The figure obtained after the transformation) and the Pre-Image (The original figure) have the same shape, but their sizes are different.
For a dilation using a scale factor "k" and centered at the origin, the rule is:
[tex](x.y)[/tex] → [tex](kx,ky)[/tex]
Let's pick the point S of the Pre-Image RSTU. This is :
[tex]S(1,1)[/tex]
And the point S' of the Image R'S'T'U' is:
[tex]S'(4,4)[/tex]
You can identify that the coordinates of S' are obtained by multiplying the coordinates of the point S by this scale factor:
[tex]k=4[/tex]
Therefore, the rule that yields this dilation is:
[tex](x.y)[/tex] → [tex](4x, 4y)[/tex]
