Answer:
A. (8, 7), B (19, −12), C (−21, 14)
Step-by-step explanation:
You swap the X and Y coordinate for reflections over y=x
Its the first choice.
You flip the coordinates so the point (a, b) shifts to (b, a). So point A (7, 8) shifts to (8.7).
x=13
15x-15
15*13=195
195-15=180
It is about 0.83 in decimal or 10 twelfths (10/12) in fraction form. I hope this helped! So sorry if it's wrong!!!
