Please help me thanks

The constant rate of change is 1.5

The point that intersects the y axis is (0,0)

Step-by-step explanation:

Constant rate of change: y2-y1/x2-x1

(1,1.5) (2,3)

3-1.5=1.5

2-1=1

1.5/1=1.5

Constant rate of change is 1.5

Hope this helps!

d

step-by-step explanation:

given

y + 3 = - 4(x - 2) ← distribute the parenthesis

y + 3 = - 4x + 8 ( subtract 3 from both sides )

y = - 4x + 5 → d

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.
