Answer:
2.
Step-by-step explanation:
Take the point K.
To get to K from the origin we move 4 to the right and up 2.5 units.
Now consider point P on the large triangle . To get to that from the origin we move 8 units to the right then up 5 units.
These distance are twice the distances we moved to get to K.
Therefore the scale factor is 2.
