Brainliest or whatnot just answer it

the answer is y=2x-3

Step-by-step explanation:

4/2=2 slope

1-4= -3 y-intercept

hope this helps!

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.
