Final answer:
The constant of proportionality from m to j in the equation j = m is 1.
Step-by-step explanation:
In the proportional relationship j = m, the constant of proportionality from m to j is 1.
A proportional relationship means that the two variables, m and j, are directly related to each other. This means that when one variable increases, the other variable increases by the same factor. In this case, since j = m, the constant of proportionality is 1.
