A biologist created the following graph to show the relationship between the temperature of water (x), in degrees
Celsius, and the number of insect larvae (y) in the water:
What does the y-intercept of the graph represent?
There were 400 larvae in the water at 0 degree Celsius.
There were no larvae in the water at 400 degrees Celsius.
The original number of larvae in the water was 400.
The original temperature of the water was 400 degrees Celsius.
