Which linear equation is modeled by the graph? A)-2x-3y=15
B)2x-3y=-15
C)2x+3y=-15
D)2x-3y=15

The answer is option A. If you observe the graph carefully...you can observe that the slope is positive and the y-intercept is -5. But it doesn't match with any in the option. That means you have to simplify every equation. For that move the X values to the right hand side then move the coefficient of y to the right hand side...that should give you the solution. This will take time and one shouldn't spend time in mcq. To save your timejust play around with signs. You can get the solution directly. we can observe that the slope is positive and if we move the positive X values then we will be getting negative slope...which ain't meeting the conditionthus we have to move the negative X to the right hand side to have positive slope...thus option a is correct.

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.
