Two similar triangles are shown on the 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′? (4 points) a Dilation by a scale factor of 4 followed by reflection about the x-axis b Dilation by a scale factor of 2 followed by reflection about the x-axis c Dilation by a scale factor of 4 followed by reflection about the y-axis d Dilation by a scale factor of 2 followed by reflection about the y-axis

Answer:

  d  Dilation by a scale factor of 2 followed by reflection about the y-axis

Step-by-step explanation:

In each case, the transformation is ...

  (x, y) ⇒ (-2x, 2y)

So, a dilation by a factor of 2 is involved. That is what multiplies the coordinates by 2. Reflection in the y-axis is what negates the x-coordinate.

The transformations are ...

  Dilation by a scale factor of 2 followed by reflection about the y-axis
