what is the equation in point-slope form of the line that passes through the point (4, "-7)" and has a slope of "-1/4"

y+7=-1/4(x-4) i think

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.  

answer: translate the circles so they share a common center point and dilate circle y by a scale factor of 3.
