Write an equation of the line that passes through (1,2) and is parallel to the line y=−5x+4

y = = -5x + 7

Step-by-step explanation:

y=−5x+4, slope = -5

Parallel lines, slopes are the same so slope of new line is also equal -5

Equation in point slope form:

y - 2 = -5(x - 1)

y - 2 = -5x + 5

y = = -5x + 7 <equation in slope intercept form

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.
