Help meeeeeeeeeeeee!!!!!

Answer:
B
Step-by-step explanation:
A constant variation graph has the following format:
[tex]y=kx[/tex]
Where k is the constant of proportionality.
Let's pick a point from the graph, say, (1,5).
Substitute 1 for x and 5 for y:
[tex]5=1(k)[/tex]
Simplify:
[tex]5=k[/tex]
Therefore, the constant of proportionality is 5.
And we're done!
