If x and y are inversely proportional then _____ = k where k is positive constant

Solution:

If x and y are inversely proportional then we can write:

x ∝ 1/y

Which implies x = k/y

xy = k

Where k is a positive constant

✦ Try This: If x and y are directly proportional then _____ = k where k is positive constant.
