Line ab passes through points a(–6, 6) and b(12, 3). if the equation of the line is written in slope-intercept form, y = mx + b, then m =–1/6 and b =
a.-6
b.-5
c.5
d.6

Step-by-step explanation:

I just took it on edge

m=−2, b=18

eqn. of a straight line with known co-ordinates

(x1,y1), (x2,y2)

is given by the formula

y−y1x−x1=y2−y1x2−x1

for A(6,6), B(12,3)

y−6x−6=12−63−6

y−6x−6=6−3=−2

y−6=−2(x−6)

y=6+(−2x)+12

y=−2x+18

m=−2, b=18

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.
