Answer:
Step-by-step explanation:
Direct variation problems can easily be solved with proportions, namely:
and cross multiply to get
2y = 20 so
y = 10
The answer would be C) Set 1 and Set 3. This is because both numbers in the set have to be negative for the statements to be true.
Answer:

3x - 7y = 9 (answer).
