Given:
(-5,14), (1,-16)
The linear regression formula is
Substitute x=1 and y=-16 in the formula, we get
Subtracting m from both sides of the equation, we get
We get
Substitute x=-5 and y=14 in the formula, we get
Substitute b=-16-m in this equation to find the value of m.
Adding 16 to both sides of the equation, we get
Dividing both sides by (-6), we get
Substitue m=-5 in b=-16-m to find the value of b.
Substitute b= -11 and m= -5 in the line equation, we get
Hence linear regression is
