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′?

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

Reason: Multiply each vertex by 2: A(-3,2) -> (-6,4), B(-1,0) -> (-2,0), C(-2,-1) -> (-4,-2). Reflecting these across the y-axis gives (6,4), (2,0), (4,-2), which are A′, B′, C′.
