Find the slope of the line that passes through -1,-3 and -9,7

m = -5/4

Step-by-step explanation:

Going right from the point (-9,7) to the point (-1,-3), we see that x increases by 8 and y decreases by 10.

Thus, the slope of the line connecting these two points is

m = rise / run = -10/8, or -5/4.

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.
