Answer 1

To find the constant of proportionality in a proportional relationship, we can use the formula k = y/x, where k is the constant of proportionality and (x, y) is any point on the graph.

In this case, the point (5, 2) is given. So, we can calculate the constant of proportionality as follows:

k = 2/5

Therefore, the constant of proportionality of the relationship is 2/5.
