Answer:
The answer is rotation 180 degrees counterclockwise about the origin.
Step-by-step explanation:
The first choice.
Looking at the other choices when u do a reflection across the y-axis then 8 units up point b doesn’t match up.
Second choice.
When you do a reflection across the x-axis you would have to do 10 units to the left not 4.
Third choice.
If u just do a rotation 90 degrees the triangle wouldn’t be in the right quadrant.
Therefore the choice is 4 the last one
