If y varies directly as x, and y = 15 as x = - 3, find y for the x-value of 6.

1. - 30

2. - 32

3. - 34

4. - 36

the answer is - 30.

Step-by-step explanation:

for each x-value, you will multiply it by - 5 to get your y-value. i say this because if y-15 when x=-3, if you divide the x from y (so 15/-3) you get - 5 which is the number in which y varies by. so you will take 6 and multiply it by - 5 which gives you - 30.
