Answer:
- are not
- is not proportional
Step-by-step explanation:
To see what multiple y is of x, divide y by x:
y/x = 3/1 = 3
y/x = 5/2 = 2.5
y/x = 6/3 = 2
The values 3, 2.5, and 2 are not all the same, so you must conclude y is not a constant multiple of x.
If the multiple is not constant, the relationship is not proportional.
