Find the​ x- and ​y-intercepts of the graph. Select the correct choice below​ and, if​ necessary, fill in the answer box to complete your choice. A. The​ x-intercept(s) is/are 2. ​(Type integers or fractions. Use a comma to separate answers as​ needed.) Your answer is correct. B. The graph has no​ x-intercept. Select the correct choice below​ and, if​ necessary, fill in the answer box to complete your choice. A. The​ y-intercept(s) is/are nothing. ​(Type integers or fractions. Use a comma to separate answers as​ needed.) B. The graph has no​ y-intercept.

Step-by-step explanation:

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.  

y = 3x+4

step-by-step explanation:

to find the slope

slope = (y2-y1)/ (x2-x1)

    = (-8-4)/ (-4-0)

    = -12/-4

  = 3

using the slope intercept form of a line

y= mx+b

we know the slope is 3

we know the y intercept is 4 ( the point where it crosses the y axis or x=0)

y = 3x+4
