Answer 2

Reflections across axis' mean that reflected identical shapes will have:

the same x coordinates if they are reflected across the x axis

the same y coordinates if they are reflected across the y axis.

These triangles already have the same y coordinates: (0) at points G, F and G', F'.

GF = 1 unit

G'F' = 4 units

4/1 = 4

Therefore, it is reflected across the y-axis with a scale factor of 4.
