How can kendra determine if the function is actually linear?
she can check to see if the rate of vertical increase equals the rate of horizontal increase between each pair of points.
she can check to see if the sum of each y-value and x-value in every ordered pair is the same.
she can check to see if the quotient of each y-value and x-value in every ordered pair is the same.
she can check to see if the rate of change between the first two ordered pairs is the same as the rate of change between the first and last ordered pairs.

D. She can check to see if the rate of change between the first two ordered pairs is the same as the rate of change between the first and last ordered pairs.

Step-by-step explanation:

Find the rate of change between first two ordered pairs and the second two ordered pairs:

1. Points (2,4) and (3,9). Rate of change:

2. Points (3,9) and (4,16). Rate of change:

The rate of change for the linear function must the same for each two points on the graph of the function. In this case, the reate of change differs, so this function is not linear and correct option is D.

the population of other specie of birds will decline or other specie of birds will find some alternate source of food to survive.

explanation:

according to the competitive exclusion principle, which is also known as gause's law, two specie living in the same niche and feeding on the same resource cannot co-exist stably.

as we have well studied the theory of natural selection which states that only those organisms survive which have better tendency to compete for food and adapt to the environmental conditions.

coming towards the question, what wi ll happen when one species outcompetes the other for the small fish , the other specie will not get enough food and will start to die or decline in population. eventually either other specie needs to find another alternative food source for itself or migrate at some other location where there is less competition otherwise it will just not exist anymore at that niche.

hope it !
