- Specialized
- In the equation y = kx, k represents the factor of proportionality.
Examples
-
In direct variation, the factor of proportionality is often denoted by the letter k.
-
When converting between units, the factor of proportionality helps ensure the quantities stay equivalent.
-
The factor of proportionality in this equation determines how y changes as x increases.
-
The factor of proportionality is essential in linear equations.
-
In the equation y = kx, the constant k is called the factor of proportionality.
-
The factor of proportionality in physics allows us to relate two different quantities.
-
Understanding the factor of proportionality is crucial for solving problems involving direct variation.
Synonyms
A number that divides another number exactly
A number that multiplies a variable or shows how strong a relationship is in math and science
A number that shows how much one value changes when another changes at the same rate
A number that makes an object bigger or smaller by the same amount

factor + of + proportionality
The noun phrase is fully compositional: 'factor' (a multiplying number) linked by 'of' to 'proportionality' (a multiplicative relation), so the meaning — the multiplicative constant relating two proportional quantities — follows directly from the constituents. This follows a common, cross-linguistic 'factor of X' pattern and would be interpretable by a B1 learner who knows the component words.
Etymology
Factor of proportionality names the fixed number that tells how two amounts change together. Think of a recipe: the factor is the number you 'multiply' the ingredients by, and proportionality means the parts stay the same, so the factor of proportionality is the number you use to 'convert' one amount into the other.
