Please Match each equation on the left to the mathematical property it uses on the right.

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.  

i believe that the answer is

b. y-1=-2(x-4)

hope this !

55 degrees because 55+55=110 degrees
