<h2>y = 2.4x - 7.8</h2>
Step-by-step explanation:
The slope-intercept from of an equation of a line:
<em>m</em><em> - slope</em>
<em>b</em><em> - y-intercept</em>
The formula of a slope:
<em>(x₁, y₁), (x₂, y₂)</em><em> - ponts on a line</em>
<em />
We have two points (7, 9) and (2, -3).
Substitute:
Put the value of the slope and the coordinates of the point (7, 9) to the equation of a line:
<em>subtract 16.8 from both sides</em>
Finally we have:
The science books can be placed before or after the English books, so that’s two ways science-English or English-science.
There are 24 ways to arrange the 4 science books and 2 ways to arrange the English books.
