The graph shows a proportional relationship between the variables x and y.

A. Write an equation to model the relationship

B. Explain how you know if an equation or a graph
represents a 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.
