What is the equation of the line, in slope-intercept form, that passes through the point (6,−1) and is perpendicular to the line y=2x−7?

a)y=2x+13
b)y=−12x+2
c)y=12x−4
d)y=12x+132

did you mean to put. y= -1/2x+2 for choice b? because that's what I got as a solution

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.  

a. 32 degrees

step-by-step explanation:

here we have to use the rule.

m∠e = 1/2 (major arc - minor arc)

m∠e = 1/2 (212 - 148)

m∠e = 1/2 (64)

m∠e = 32 degrees

answer: a. 32 degrees
