What is the image of [tex]\((-12, 4)\)[/tex] after a dilation by a scale factor of [tex]\(\frac{1}{4}\)[/tex] centered at the origin?



Answer :

To find the image of the point [tex]\((-12, 4)\)[/tex] after a dilation by a scale factor of [tex]\(\frac{1}{4}\)[/tex] centered at the origin, follow these steps:

1. Identify the original coordinates of the point:
[tex]\[ (x, y) = (-12, 4) \][/tex]

2. Identify the scale factor:
[tex]\[ k = \frac{1}{4} \][/tex]

3. Apply the scale factor to the x-coordinate:
[tex]\[ x' = x \cdot k = -12 \cdot \frac{1}{4} = -3 \][/tex]

4. Apply the scale factor to the y-coordinate:
[tex]\[ y' = y \cdot k = 4 \cdot \frac{1}{4} = 1 \][/tex]

5. Combine the new coordinates to get the image of the point after dilation:
[tex]\[ (x', y') = (-3, 1) \][/tex]

Therefore, the image of the point [tex]\((-12, 4)\)[/tex] after a dilation by a scale factor of [tex]\(\frac{1}{4}\)[/tex] centered at the origin is [tex]\((-3, 1)\)[/tex].
