Find the correlation coefficient, r, of the data described below. A publishing company is interested in the relationship between a customer's educational background and book-buying habits. As part of his summer internship at the company, Chase designed a survey to investigate this relationship. The survey asked each person how many years of education they had completed, x, and how many books they had purchased last year, y. Years of education Books purchased last year 14 10 14 1 17 24 18 48 20 69 Round your answer to the nearest thousandth. r=

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)

600,000,000,000, or 6e14

step-by-step explanation:

slope =   (y2 -y1) ÷ (x2 -x1)

slope = (0 -0) / (-5, -7)

slope = 0 / -12 = 0

the slope of the line is zero.   it is perfectly horizontal.
