Question

A regression line contains the point (21.02, 35.5). The slope of the regression line is approximately 3.1. What is the equation of the regression line?

Answer 1

C) y = 3.1x - 29.66

Step-by-step explanation:

Answer 2

Y = 3.1X --29.66. (Y -- 35.5) / (X -- 21.02) = 3.1 Now solve for Y; therefore, Y = 3.1( X -- 21.02) + 35.3, which gives Y = 3.1X --29.66. This will cross the y-axis at --29.66, and the X-axis at about 9.57
