Question 8 of 13
2 answers:
The line of best fit is y = -0.223x + 24.081
<h3>Linear equation</h3>
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

Linear regression are used to represent scatter plots
The linear regression equation is:
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:
