Given: the points ( 0.5 , 1/10 ) and ( 7 , 1 2/5)

The points are on the graph of a proportional relationship

It is required to find the constant of proportionally

so, the graph of the points will be as shown in the following image:

as shown there a proportional relationship

Because the line is pass through zero

So, the constant of proportionality = y/x

It can be calculated using any point from the given points

So ,

Using the point ( 0.5 , 1/10)

the constant = 0.1/0.5 = 0.2

We can check the answer using the other point ( 7, 1 2/5)

The constant = (1 2/5)/7 = 1.4/7 = 0.2

So, the constant of proportionality = 0.2
