The constant of proportionality is 5 y 5x When we know the constant of proportionality we can then answer other questions Example continued What is the value of y when x 9 y 5 9 45 What is the value of x when y 2 2 However this is not always the case x and y are directly proportional if y kx where k is a constant x and y are inversely proportional if y k x k is constant This is the
The proportional relation equation is eq y kx eq The letters y and x are the variables which can change and the letter k is the constant of proportionality Identifying Proportional Relationships When quantities are proportional their ratios are equal For example the ratios frac 2 5 and frac 8 20 are proportional
