13) Which graph represents a non-proportional relationship?

B

Step-by-step explanation:

Proportional relationships go through the origin (0,0) and have a constant rate of change.

Regarding proportional relationships, when graphed the line should be straight and go through the origin (0,0)

All graphs appear to have straight lines.

However graph B has a line that doesn't go through the origin, therefore B represents a non proportional relationship

the red lines denote the population of the bacteria after 35 hours. that would be 2,409.24. the y-intercept is the blue line which is 800 because that is the starting point. the equation used to make the graph is 800(1.032)^h, where h is the number of hours.
