Answer:
The correct option is 1.
Step-by-step explanation:
It is given that the box plot shows the number of books sold each day at a store for 80 days.
A box plot is drawn with end points at 0 and 16. It means minimum value is 0 and maximum is 16.
The box extends from 2 to 12. It means first quartile is 2 and the third quartile is 12. A vertical line is drawn inside the box at 7, it means median is 7.
He have to find the number of days in which the bookstore sell 2 to 12 books.
2 is first quartile and 12 is third quartile, we know that
The data lies between Q₁ and Q₃ is 50% of the data.
The bookstore sell 2 to 12 books in 40 days.
Therefore, the correct option is 1.

Answer:
y = x - 8
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
y = - x - 1 ← is in slope- intercept form
with slope m = -
Given a line with slope m then the slope of a line perpendicular to it is
= -
= -
=
The equation of a line in point- slope form is
y - b = m(x - a)
where m is the slope and (a, b) a point on the line
Here m = and (a, b) = (9, - 2), thus
y - (- 2) = (x - 9), that is
y + 2 = (x - 9) ← in point- slope form
Distribute right side and rearrange
y + 2 = x - 6 ( subtract 2 from both sides )
y = x - 8 ← in slope- intercept form
