Hint: Use the distance formula:
d= (x2 - 1)2 + (y2 - y.)2

slope = - 2

Step-by-step explanation:

Calculate the slope m using the slope formula

m =

with (x₁, y₁ ) = A (- 1, 2) and (x₂, y₂ ) = B (1, - 2)

m = = = = - 2

what "following statement"?

step-by-step explanation:

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.
