Answer:
the right answer is the constant of proportionality
Step-by-step explanation:
The unchanging value of the ratio between two proportional quantities is the constant of proportionality.
INTERPRETATION----
Lets say a is directly proportional to b and k is a constant.
- This can be expressed as;
- a ∝ kb
- This means that as the value of a rises, the value of b rise too.
- k (the constant of this proportionality remain the same)
OR
If two variables are related and this relationship is that there is a constant ratio between them, then we are talking about proportionality. There are two types of proportionality.
1) Direct Proportionality:
In a mathematical language this is given by this equation:
[tex]y = kx[/tex]
where k is in fact this constant of proportionality. If x increases, y also increases at the same rate.
On the other hand, If x decreases, y also decreases at the same rate.
2) Inverse Proportionality:
In a mathematical language this is given by this equation:
[tex]y=\frac{k}{x}[/tex]
where k is also called the constant of proportionality. If x increases, y decreases at the same rate. On the other hand, If x decreases, y increases at the same rate.
