Two similar triangles are shown on the coordinate grid:

a coordinate plane is shown. triangle xyz has vertices x at negative 5 comma negative 1, y at negative 6 comma negative 2, and z at negative 3 comma negative 2. triangle x double-prime y double-prime z double-prime has vertices x double-prime at 10 comma negative 2, y double-prime at 12 comma negative 4, and z double-prime at 6 comma negative 4.

which set of transformations has been performed on triangle xyz to form triangle x”y’’z’’?

dilation by a scale factor of 4 followed by reflection about the x-axis
dilation by a scale factor of 2 followed by reflection about the y-axis
