Answer:

n = 5

Step-by-step explanation:

m = (y₂ - y₁) / (x₂ - x₁)

m = (1 - (-8)) / (n - 2)

3 = ( 1 + 8 ) / ( n - 2)

3 = 9 / ( n - 2)

n - 2 = 9 / 3

n - 2 = 3

n = 3 + 2

n = 5

Answer:

$\frac{3}{20}$

Step-by-step explanation:

Let x be the cover page

We are given that a newspaper 's cover page is $\frac{3}{8}$ text and photograph fill the rest.

We have to find that how much part of cover's page is the article about endangered species

Text = $\frac{3}{8}x$

Remaining part = $x-\frac{3}{8} x$

Remaining part = $\frac{8x-3x}{8}=\frac{5}{8} x$

Therefore, a newspaper;s cover page fill with Photograph = $\frac{5}{8}$

If the article about endangered species= $\frac{2}{5}$ of text

Therefore, the article about endangered species= $\frac{2}{5}\times\frac{3x}{8}=\frac{3}{20}x$

Hence, the article about endangered species is $\frac{3}{20}$ of the cover page.
