Answer:
[tex]\huge\boxed{\sf k =3}[/tex]
Step-by-step explanation:
Graph shows that:
y ∝ x (y is directly proportional to x)
Changing proportionality into equality
y = kx ------------(1)
Where k is the constant of proportionality
From the graph, we have y = 6 when x = 2
Putting this in Eq. (1)
6 = k(2)
Divide both sides by 2
3 = k
OR
k = 3
[tex]\rule[225]{225}{2}[/tex]
