Answer 2

B.
`(3,15)`

E.
`(-1,-5)`

Explanation:

we have

`y=5x` -----> represent a linear direct variation

we know that

A relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form
`y/x=k` or
`y=kx`

In this problem we have

`k=y/x=5`

Verify each case

Point A
`(0,1)`

`k=y/x=1/0` ----> k is undefined

Point B
`(3,15)`

`k=y/x=15/3=5` -----> the point is on the given line

Point C
`(4,2)`

`k=y/x=2/4=0.5` -----> the point is not on the given line

Point D
`(3,6)`

`k=y/x=6/3=2` -----> the point is not on the given line

Point E
`(-1,-5)`

`k=y/x=-5/-1=5` -----> the point is on the given line

Point F
`(-1,5)`

`k=y/x=5/-1=-5` -----> the point is not on the given line
