Answer:
Here, <em>e</em> is the proportionality constant.
Step-by-step explanation:
Two quantities P and q are said to in proportion if and only if they have equivalent fraction in each case.
or,
for each value of P and Q.
Here, k is called the Proportionality Constant.
Now here given: x and y are in proportion.
also, y = ex
⇒
So, here e is the proportionality constant.
