Lenny asked five of his friends how many pencils they had in their pencil bag. his teacher said students never bring pencils to class. which of the following statement could he use to convince her that she is wrong based on his graph?

a.

most students brought 6 pencils to class.
b.

the mean number of pencils that these five students brought to class is 6 pencils. c.

the mean number of pencils that these five students brought to class is 10 pencils.
d.

the mean number of pencils that these five students brought to class is 4 pencils.

goog may be able to you find that answer

c. y = 1/4 x + 5

step-by-step explanation:

first, put the equation of the line on the graph into slope-intercept form

(y = mx + b):   y = -4x + 8

second, a perpendicular line has to have "an opposite/reciprocal slope" to the original slope. so, find the "m" value in your original equation (it's -4, right? )

original slope: m = -4   perpendicular slope: change the sign to its opposite and find the reciprocal ("flip" the number)

new slope is now positive (b/c the original slope was negative 4), and it's 1/4 (not the original slope of 4 or 4/1)
