Answer:
Option D
Explanation:
Property of a proportional relationship,
y ∝ x
y = kx
Where 'k' is the proportionality constant
This equation represents a line with no y-intercept.
Therefore, all the lines having y-intercept will not show the proportional relationship.
From the graph attached,
Green and pink lines have no y-intercepts.
Therefore, green and pink lines represent the proportional relationship.
Option D is the correct option.
