y=mx+b

step-by-step explanation:

m slope

b y-intercept

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.  

my guess would be b and d, but i didn’t actually get out the pen and paper. lol

m∠a is 90°

m∠b is 40°
