Question

Hi someone pls pls pls help a kid out.

Two similar triangles are shown on the coordinate grid:

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 1

Option C stands correct because the ∆ E'F'G' is formed by firstly expanding the triangle by a factor of 4 and then obtaining its reflection about the y axis, i.e. by changing the signs of abscissa.
