How does one solve this question, any would be appreciated! i feel this has a really easy solution and i've decided to significantly over-complicate it.

13. a) write down the equation of the line with gradient 3 passing through (0, -2)

b) write down the equation of the line which is parallel to the line y=4-5x passing through (0,-1)

correct answer:

i^31 = -i

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.
