Question

Use the graph to find the constant of proportionality of the number of books printed per hour a printing press. *1. 5/49 = 1/92. 49/5 = 9/13. 16/14. 1/165. Other:

Answer 1

Constant of proportionality: slope

Apply the slope (m) formula:

`m=(y2-y1)/(x2-x1)`

Replace by 2 points represented on the graph, for example:

Point 1= (5,49)

Point 2 = (14,126)

Replacing;

`m=(126-49)/(14-5)=(77)/(9)`

77/9 , simplify :
