Based on the regression line, and the data points, the sum of squared residuals is 22.
The squared residual can be found as:
= (y - 3 + 2x)²
For point (4 , 8)
= (8 - 3 - 2(4))²
= 9
For point (2 , 5)
= (5 - 3 - 2(2))²
= 4
For point (1, 2)
= (2 - 3 - 2(1))²
= 9
The sum of squared residuals is:
= 9 + 4 + 9
= 22
