In the graph, the constant of proportionality is 40
Calculating the constant of proportionality
From the question, we are to determine the constant of proportionality
The constant of proportionality = [tex]\frac{y}{x}[/tex]
From the graph, a point on the line is (1, 40)
That is,
When x = 1 and y = 40
Thus,
The constant of proportionality = [tex]\frac{40}{1}[/tex]
Constant of proportionality = 40
Hence, the constant of proportionality is 40
