It is the speed, which must be maintained at a constant value.
If the equation is y = kx then the constant of proportionality is k.

Direct proportions may be represented by a straight line through the origin, with the equation y = kx. The gradient of the line is the constant of proportionality and is a measure of the change in the "dependent" variable for a unit change in the "independent" variable. In the case of an inverse proportionality, the graph is a hyperbola with the equation y = k/x. The constant of proportionality, k, is a measure of the change in the reciprocal of the "dependent" variable for a unit change in the "independent" variable.
In a table, divide a number in one column by the corresponding number in the other column. In a graph it is the gradient of the line. The equation, for the variables X and Y will be of the form Y = mX and the constant of proportionality is m.
The linear function has the form y=mx+b, which I expect you have heard of. The 'b' is the y-intercept, and the 'm' is the slope. A constant of proportionality is something you have with direct variation, which is where the line goes through (0,0). This happens when 'b' equals zero. So now the equation is just y=mx, and the constant of proportionality is 'm'.

To identify a unit rate or constant of proportionality in a table, look for a consistent ratio between two quantities, where one quantity is typically expressed per unit of the other. In a graph, the constant of proportionality is represented by the slope of the line; if the line passes through the origin, the slope indicates the unit rate. In an equation of the form (y = kx), the constant (k) represents the constant of proportionality, indicating how much (y) changes for each unit increase in (x).

Yes, a proportionality constant can have dimensions, depending on the relationship it describes. For example, in the equation ( F = kx ) (where ( F ) is force, ( k ) is the proportionality constant, and ( x ) is displacement), the constant ( k ) has dimensions of force per unit displacement. However, in some relationships where quantities are dimensionless, the proportionality constant may also be dimensionless.
v = H0D Where v is the velocity at which a galaxy moves away from us, and D is its distance. With H0 being the constant of proportionality (the Hubble constant) between the distance D to a galaxy and its velocity v.
y = cx where c is the constant of proportionality.
y = kx where k is a non-zero constant is an equation of direct proportionality between x and y.
In a table, divide a number in one column by the corresponding number in the other column. In a graph it is the gradient of the line. The equation, for the variables X and Y will be of the form Y = mX and the constant of proportionality is m.
y = c*x3 where c is the constant of proportionality.
In the equation ( y = 4X ), the constant of proportionality is 4. This means that for every unit increase in ( X ), ( y ) increases by 4 units, indicating a direct proportional relationship between ( y ) and ( X ). Thus, ( y ) is directly proportional to ( X ) with a proportionality constant of 4.
The constant of proportionality in the equation y = 3.8x is 3.8. This means that for every unit increase in x, y will increase by 3.8 times that amount. It represents the ratio between the two variables and remains constant throughout the relationship.
