I will do this one. You can then use my notes to solve question 2.
Ready?
If x varies directly with y, we can write the equation like x = yk, where k represents the constant of variation.
The constant ratio is called the constant of variation.
You are given x = 4 and y = 16.
Plug those two values into the equation given above and solve for k.
x = yk
4 = 16k
Divide both sides by 16.
4/16 = k
1/4 = k
Did you follow?
Now, do the next question exactly the same way.
If you cannot, then write back.
