The German word konstant
If something called F is proportional to xyz, then you could write F=kxyz. Which means that however much x, y or z change there is a value, labelled "k", unknown, that always stays the same. And if you know one set of values of F,x,y and z then you can work out what k is.

If y equals kx then what is the relationship between x y and k?
Various options: y is directly proportional to k, with x as the constant of proportionality; y is directly proportional to x, with k as the constant of proportionality; x is inversely proportional to k, with y as the constant of proportionality; x is directly proportional to y, with 1/k as the constant of proportionality; k is directly proportional to y, with 1/x as the constant of proportionality; and k is inversely proportional to x, with y as the constant of proportionality.
In a direct proportion y kx the number k is called the constant of .?
It is the constant of proportionality.
What does k mean in math?
It depends on the context. It can mean 1000 (as in kilo). It can represent a constant, specially a constant of proportionality. It can represent a unit vector in the third mutually perpendicular direction (the z-axis). It is often used as an index (often after i and j).
What is the linear equation used to represent a proportion?
y = cx where c is the constant of proportionality.
If y 75 when k15 (constant of proportionality) what is x?
When there is a direct proportionality y = kx y = 75 k = 15 → 75 = 15x → x = 75/15 = 5
