Answer:
Proportional relationship:
Use a pair of points (0.14, 0.7) to find the value of k:
- 0.7 = 0.14k
- k = 0.7/0.14
- k = 5
The function is:
Fill in the table:
- x = 3.1 ⇒ y = 5*3.1 = 15.5
- x = 2.5 ⇒ y = 5*2.5 = 12.5
- x = 1.2 ⇒ y = 5*1.2 = 6
- x = 0.9 ⇒ y = 5*0.9 = 4.5
- y = 0.3 ⇒ x = 0.3/5 = 0.06
- y = 0.1 ⇒ x = 0.1/5 = 0.02
