Step-by-step explanation:
We can perform a least squares regression model in Ms. Excel to determine the equation of the line of best fit for the data given;
The first step is to enter the data into any two adjacent columns of an excel workbook. Next, click on the Data ribbon followed by the Data Analysis tool pack. We then proceed to select regression from the pop-up window. The final step is to select the y range and the x range of values from our data.
Once we click ok, Excel returns our least squares regression model as shown in the attachment below.
The coefficient of X variable 1 is our slope.
Answer:
if you draw LMN in the first quadrant, you need to draw L'M'N' in the third quadrant using the same coordinates as LMN but in the negative form.
The line you draw trough L and L' and both other two lines all go through the origin.
