Answer:
C. 3
Step-by-step explanation:
The constant of proportionality is the slope (or rate of change) of the graph.
To find the equation of the graph;
Take points (1,3) and (3,9)
The slope (m) = change in y ÷ change in x
m =
Taking another point (x,y) on the graph;
m =
y - 3 = 3x - 3
y = 3x + 0
y = 3x
This can be expressed as;
y ∝ 3x
Which means that as y rises, x rises too but 3 remains the same. The value 3 is the constant of proportionality in this relationship.
