Answer :

Rule for a dilation with center (0,0)

[tex](x,y)\rightarrow(kx,ky)[/tex]

k is the scale factor.

For point P (0,3):

[tex]\begin{gathered} P(0,3)\rightarrow P^{\prime}(2(0),2(3)) \\ P(0,3)\rightarrow P^{\prime}(0,6) \end{gathered}[/tex]Then the coordiantes of point P after the dilation are (0,6)
