Scatter plots show the correlation between variables on a graph

  • The slope is -1.5
  • The unit of the slope is the website visit per age
  • The slope tells that you can expect a typical 1.5 less visits each day
  • The y-intercept is 120
  • The unit of the y-intercept is website visit

How to determine the slope and the y-intercept

The function is given as:

Predicted Web Sites Visited per Day =120−1.5 ⋅ Age

A linear regression equation is represented as:

y =mx + b

Where m represents the slope, and b represents the y-intercept

Hence, the slope is -1.5 and the y-intercept is 120

How to determine the units

The slope is the quotient of the y-axis and the x-axis.

Hence. the unit of the slope is the website visit per age and the unit of the y-intercept is website visit
