how do you get the constant of proportionality?
41464
The constant of proportionality k is given by k=y/x where y and x are two quantities that are directly proportional to each other. Once you know the constant of proportionality you can find an equation representing the directly proportional relationship between x and y, namely y=kx, with your specific k.

Synonyms for (noun) constant of proportionality Synonyms: constant of proportionality, factor of proportionality. Definition: the constant value of the ratio of two proportional quantities x and y; usually written y = kx, where k is the factor of proportionality.

The value of this constant is called the coefficient of proportionality or proportionality constant. If the ratio (yx) of two variables (x and y) is equal to a constant (k = yx), then the variable in the numerator of the ratio (y) is the product of the other variable and the constant (y = k⋅x).

In mathematics, proportionality indicates that two quantities or variables are related in a linear manner. If one quantity doubles in size, so does the other; if one of the variables diminishes to 1/10 of its former value, so does the other.

When two quantities are directly proportional, they increase and decrease at the same rate. While these two quantities may increase or decrease, the constant of proportionality always remains the same.

How to tell the difference: A proportional table has a constant of proportionality in that y divided by x always equals the same value. A non-proportional table will have different values when y is divided by x.

Ratios are proportional if they represent the same relationship. One way to see if two ratios are proportional is to write them as fractions and then reduce them. If the reduced fractions are the same, your ratios are proportional. To see this process in action, check out this tutorial!

If you don't have a graph, you can tell if 2 variables are directly proportional by writing down the equation of the line. If you can use algebra to rewrite the equation to read y=kx, wherein y = the y coordinate, k = the constant, and x = the x coordinate, then the variables are directly proportional.
