Question

The regression equation y = 1.3x + 6.8 approximates the number of minutes it takes an employee to drive to work, y, given the number of miles the employee has to drive, x.

Which statement is true?
For every extra mile an employee drives, the driving time increases by 6.8 minutes.
For every extra mile an employee drives, the driving time increases by 1.3 minutes.
For every extra minute an employee drives, the distance increases by 6.8 minutes.
For every extra minute an employee drives, the distance increases by 1.3 minutes.

Answer 1

for every extra mile an employee drives, the driving time increases by 1.3 minutes

Answer 2

Answer:

For every extra mile an employee drives, the driving time increases by 1.3 minutes.

Step-by-step explanation:

The linear equation has the form y = mx + b, where

y = dependent variable = minutes it takes an employee to drive to work

m = slope = 1.3 = factor that multiplies the variable x.

x = independent variable = number of miles the employee has to drive

b = y-intercept = Constant = 6.8 = value at the point where the line crosses the and axis.

With m = 1.3, and "x" the number of miles the employee has to drive, then we can conclude that for every extra mile an employee drives, the driving time increases by 1.3 minutes.

 

Hope this helps!
