Y=10
Add 10 to both sides
-5y=-50
Then divide both sides by -5
y=10
Add 10 to both sides
-5y=-50
Then divide both sides by -5
y=10
Answer:
The equation of the regression line is:
Step-by-step explanation:
The Least Squares Regression Line is the line that makes the vertical distance from the data points to the regression line as small as possible. It’s called a “least squares” because the best line of fit is one that minimizes the variance.
We have the following data:
To find the line of best fit for the points:
Step 1: Find and
as it was done in the table
Step 2: Find the sum of every column:
Step 3: Use the following equations to find a and b:
Step 4: Assemble the equation of a line
The graph of the regression line is:
