Answer:
LETTER B (decreases)
Step-by-step explanation:
To distinguish if what happens to the value of y. We will test some points:
When x = 1
- 5x + y = 7
- 5(1) + y = 7
- 5 + y = 7
- y = 7 - 5
- y = 2
When x = 2
- 5x+y = 7
- 5(2)+y = 7
- 10+y = 7
- y = 7 - 10
- y = -3
When x = 3
- 5x + y = 7
- 5(3) + y = 7
- 15 + y = 7
- y = 7 - 15
- y = -8
Noticing the behavior of the test points. As x increases , the value of y decreases.
