If we look at the graph this is an increasing graph where y increases with respect to x so in other words we can say that y is directly proportional to x.

$y\ \alpha\ x\\$

and when we remove the proportionality sign we replace it with an equal to sign and a constant. So it becomes ,

$y = kx\\$

now to find the Constant of proportionality which is k we can use any ordered pair(coordinate/point) from the graph,

Lets take ( 2 , 4) where 2 represents the value of x on the x-axis and 4 represents the value of y on the y-axis so now,

$y=kx\\(4)=k(2)\\4=2k\\4/2=k\\k=2\\$

so the constant of proportionality is 2
