Write an equation of a line that passes through the point (-9,2) and is perpendicular to the line y=3x-12 A. y=-3x+12
B. y=(1/3)x-2
C. y=(-1/3)x-1
D. y=3x-1

Step-by-step explanation:

perp. -1/3

y - 2 = -1/3(x + 9)

y - 2 = -1/3x - 3

y = -1/3x - 1

answer is C

they can both be solutions depends on the equation

step-by-step explanation:

what is the equation? ?

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.
