The constant of proportionality of the proportional relationship is: kk = 5/4
Constant of Proportionality of a Proportional Relationship
Where, x and y are the variables in a proportional relationship, the constant of proportionality is given as k = y/x.
Given a point on the proportional graph, (2/5, 1/2):
x = 2/5
y = 1/2
Therefore:
k = 1/2 ÷ 2/5
k = 1/2 × 5/2
k = 5/4
Therefore, the constant of proportionality of the proportional relationship is: kk = 5/4
