Linear regression are used to represent scatter plots

The linear regression equation is: [tex]y = -0.223x + 24.081[/tex]

How to determine the linear equation

Start by entering the table values in a graphing calculator.

From the graphing calculator, we have the following calculation summary

  • Sum of X = 15
  • Sum of Y = 117.06
  • Mean X = 3
  • Mean Y = 23.412
  • Sum of squares (SSX) = 10
  • Sum of products (SP) = -2.23

Hence, the linear regression equation is:

[tex]y = -0.223x + 24.081[/tex]

The line of best fit is y = -0.223x + 24.081

Linear equation

A linear equation is in the form:

y = mx + b

where y, x are variables, m is the slope of the line (rate of change) and b is the y intercept (initial value of x).

Plotting the values of the table using geogebra online graphing tool, the line of best fit is y = -0.223x + 24.081
