What is the slope of -4,5 & 1,-7.5

The slope is 0.5

Step-by-step explanation:

use the slope formula

x1 y1 x2 y2

( -4 , 5 ) ( 1 , 7.5 )

y2 - y1

x2 - x1

0 is its x and y coordinate

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.
