Answer:
C)

Explanation:
The proportional equation is given by :

where
represents constant of proportionality.
The value of
can be found out by dividing the
-value by the corresponding
-value.

The points on graph is given as:
(0,0),(2,6),(12,4),(18,6) and (24,8)
So, the value of
using point (2,6) can be calculated as :

∴

Thus the proportional relationship of the graph is given by :
