Answer:
The constant of proportionality is 150. This means that the paper-folding machine can fold 150 sheets of paper per minute.
Step-by-step explanation:
To find the constant of proportionality find two points on the graph (in this example I'll use (0, 0) and (20, 3000)) and put them into this expression: [tex]\frac{y2-y1}{x2-x1}[/tex]
[tex]\frac{3000-0}{20-0}[/tex]
3000 - 0 = 3000
20 - 0 = 20
[tex]\frac{3000}{20}[/tex] = 150
The constant of proportionality is 150.
