Question

If rectangle DEFG is dilated by a scale factor of 3 with a dilation center of (0, 0), what will be the coordinates of point D'?

Answer 1

The answer is C (-6,-3).
Take the ordered pair and multiply by 3.
(-2,-1)*3= (-6,-3)

Answer 2

The correct option is $\boxed{\bf option C}$ i.e., $\boxed{\bf (-6,-3)}$.

Further Explanation:

Given:

There is a rectangle DEFG on a cartesian plane and the points are $\text{D}(-2,-1)$, $\text{E}(-2,1)$, $\text{F}(2,1)$ and $\text{G}(2,-1)$.

The objective is to find the coordinates of the point D when it is dilated by the factor of $3$ with dilated center of $(0,0)$.

Dilation means it is a transformation which produces images which is having same shape as original but it is of different size.

The description of dilation includes scaling factor and dilation center.

As we know dilating the figure by the scale factor of $k$ then we will multiply the coordinates of all points of the figure by the scaling factor $k$ such that,

$\boxed{(x,y)\rightarrow(kx,ky)\text{ (after dialation)}}$

It can be seen that the coordinates of point D are $(-2,-1)$ and after dilation by the scale factor of $3$, the coordinates of D gives D' and it can be written as follows:

$\boxed{\left((-2\cdot 3),(-1\cdot 3)\right)\rightarrow(-6,-3)}$

Therefore the coordinates of point D after dilation will be $(-6,-3)$ and can be seen in figure 1 (attached in the end).

Thus, the correct option is $\boxed{\bf option C}$ i.e., $\boxed{\bf (-6,-3)}$.
