Question

Write the coordinates of the vertices after a dilation with a scale factor of 1/2, centered at the origin.L (-2, 14)L' (___,___)

Answer 1

Problem:

Write the coordinates of the vertices after a dilation with a scale factor of 1/2, centered at the origin.

L (-2, 14).

Solution:

To dilate something in the coordinate plane, multiply each coordinate by the scale factor. This is called mapping. Then we have that the dilated coordinate is:

$L^{\prime}(-2.\frac{1}{2},14.\frac{1}{2})$

this is equivalent to say:

$L^{\prime}(\frac{-2}{2},\frac{14}{2})\text{ = }L^{\prime}(-1,7)\text{ }$

Then, the correct answer is:

$\text{ }L^{\prime}(-1,7)\text{ }$
