Answer:

yes, 10

Step-by-step explanation:

For a graph to represent a proportional relationship, you need 2 things:

1) The graph is a straight line that passes through the origin.

2) The line is not vertical or horizontal.

Here you have a line that is not vertical or horizontal; and passes through the origin (the point (0, 0)  ). Therefore, this line represents a proportional relationship.

To find the constant of proportionality, look for any point except the origin, and divide its y-coordinate by its x-coordinate. The constant of proportionality is also the slope of the line.

For example, pick (1, 10).

constant of proportionality = 10/1 = 10

Answer: yes, 10
