Answer:
Triangle 2 is a transformation from Triangle 1, and has been reflected across the x-axis.
Step-by-step explanation:
We can conclude that Triangle 2 is a reflection across the x-axis because the x values stayed the same but the y values are negative.
In a reflection across the x-axis, the x values will stay the same. But, since it is flipped across the x-axis, the y values will become negative.
So, Triangle 2 is a reflection across the x-axis.
