Yes, the slope of any graph where y is directly proportional to x will give you the constant of proportionality k such that y = kx. If you think about it, it will make sense. The run is a x-value(we measure it along the x-axis). So, Rise/Run can be thought of as y/x.

It is the ratio of the amounts y and x: k = y/x. Put another way: y = kx. Example: you are paid $20 an hour. The constant of proportionality is 20 because: Pay = 20 × Hours worked.

In mathematics, two varying quantities are said to be in a relation of proportionality, if they are multiplicatively connected to a constant; that is, when either their ratio or their product yields a constant. The value of this constant is called the coefficient of proportionality or proportionality constant.

We call the ratio between two directly proportional quantities the constant of proportionality. 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.

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.

The triangle proportionality theorem states that if you draw a line constructed parallel to one side of a triangle intersects the other two sides of the triangle and divides the remaining two sides proportionally.

Using the Constant of Proportionality to Solve Word Problems 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. This equation can then be used to solve for other unknown quantities.

y results from something being multiplied by x , and the values are always proportional to one another. Notice that putting these points into a ratio of x-value to y-value results in 1:3 as a simplified version. So, the constant of proportionality is what x is being multiplied by to get y . In this case, it is 3 .
