What are the two equations that apply to the points?

The answer is:

The explanation is shown below:

1. You have the following formula for calculate the slope:

2. The points given in the problem are:

(5,-2) and (-3,1)

Therefore:

3. When you substitute these values into the formula for calculate the slope, you obtain:

(The first option)

4. You can also use the following formula for calculate the slope:

5. When you substitute values, you obtain:

 (The fourth option)

the answer is; biodiversity resulting from few ancestors

adaptive radiation occurs when a population is subjected to a large natural environment with spatial ecological variations. the parts of the population in the different ecologies begin to adapt to their local environments. due to non-random mating across the large populations, this causes the different populations from the large population to speciate within their local environments. they, therefore, diverge to different species sharing a common ancestor.
