direct variation
y = kx
substitute in and solve for k
14 = k(-4)
14/-4 =k
k = -7/2
y = -7/2 x
y = -7/2 * -6
y = 42/2 = 21

So that's why it's the first one.
Hope this helps!
Answer:
24 drops of yellow paint
Step-by-step explanation:
We have a ratio of red paint to yellow paint
red:yellow

red:yellow
5*3 8*3
15 : 24
We need 24 drops of yellow paint
