HELP MY RSM CLASS IS TOMORROW Graph the lines given by the following equations:

y=3-1/2x

To calculate the y position given an x value, multiply the x value by -2 and subtract 3.

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.
