100 points!! ASAP (Will mark brainliest if right.)
Two similar triangles are shown on the following coordinate grid:

A coordinate plane is shown. Triangle ABC has vertices A at negative 3 comma 2, B at negative 1 comma 0, and C at negative 2 comma negative 1. Triangle A prime B prime C prime has vertices A prime at 6 comma 4, B prime at 2 comma 0, and C prime at 4 comma negative 2.

Which set of transformations has been performed on triangle ABC to form triangle A′B′C′?

A. Dilation by a scale factor of 4 followed by reflection over the x-axis

B. Dilation by a scale factor of 2 followed by reflection over the x-axis

C. Dilation by a scale factor of 4 followed by reflection over the y-axis

D. Dilation by a scale factor of 2 followed by reflection over the y-axis

Answer:

Reflection across the y-axis and a dilation by a factor of 2.

Step-by-step explanation:

Comparing the points from the pre-image, ABC, to the image, A'B'C', we see that both x- and y-coordinates seem to be doubled from the pre-image to the image. However, the sign of the x-coordinates in the image is different; this means that the x-coordinates are negated.  A reflection across the y-axis will negate the x-coordinates.

To double both the x- and y-coordinates, we would then apply a dilation by a factor of 2, as the scale factor gets multiplied by every coordinate.
