Please help find slope

Select two points

7/-2 and 5/-1

subtract y1 from y2 to figure out y's change

7 - 5 = 2 change in y

now we subtract x1 from x2 to figure out x's change

-2 - ( -1 ) = -1 change in x

The slope will just be the results of the change in y and x but in the order of rise/run

2/-1 = -2 is the slope

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.

step-by-step explanation:

from this example, we can see that subtracting with integers is the same as adding the opposite. we can solve using a number line or by using the saying "keep, change, change" to us solve. it is important to remember that we can subtract a negative and end up with a larger number than we started with.
