Answer:
No, the graph does not represent a proportional relationship
Explanation:
The equation that models a proportional relation is
, where k is the constant of proportionality.
Based on your description, we have:
x y
0 4
2 8
3 12
4 16
The graph of a proportional relation will always pass through the origin i.e the initial value is always zero.
The equation of this graph is not in the form y=kx.
Hence, the graph does not represent a proportional relationship because there is an initial value which is not zero.
