The constant of proportionality in the equation c = 8m will be; 8.
A variation is a relation between a set of values of one variable and a set of values of other variables. Direct variation. In the equation y = mx + b, if m is a nonzero constant and b = 0, then you have the function y = mx (often written y = kx), which is called a direct variation.
We have been given C = 8m is an equation and the relationship between c and m is direct.
This means that dividing both sides of the equation by m, we have;
C/m = 8m/m
c/m = 8
Therefore, the constant of proportionality is 8
It is found that the constant of proportionality for which c = 8m will be 8.
