Answer:
B
Step-by-step explanation:
Rotation 180° is accomplished by negating both the x- and y-coordinates. That is, you multiply each of them by -1. You want the opposite of the identity matrix, so matrix B.
The correct answer is B) y = 120000x + 420000.
We multiply 120,000 by x since that is the cost per person per day, and x is the number of days. We add 420,000 because that is the one time cost of the round trip airfare.
