The image of point P after the dilation is A (-2.5, 5)

To find the image of point P after a dilation with center (0, 0) and a scale factor of 2.5, you can use the following formulas for dilation:


\[ x' = k \cdot x \]\\ y' = k \cdot y \]

where k is the scale factor.

Let's apply these formulas to point P:

Given point P: (-1, 2)


\[ x' = 2.5 \cdot (-1) \]


\[ y' = 2.5 \cdot (2) \]

Calculating these values:

x' = -2.5

y' = 5

So, the image of point P after the dilation is (-2.5, 5). Therefore, the correct answer is: A. (-2.5, 5)
