Answer: a=1.16 and b=0.12
Step-by-step explanation:
We know that the residual value= given - predicted
For x=3
The given value =1.1
The residual value=-0.06
Thus
The predicted value (a)= given- residual
[tex]\Rightarrow\ a=1.1-(-0.06)\\\Rightarrow\ a=1.1+0.06\\\Rightarrow\ a=1.16[/tex]
For x=4
The given value =3.1
The predicted value = 2.98
Thus
The residual value (b) = given - predicted
[tex]\Rightarrow\ b=3.1-2.98\\\Rightarrow\ b=0.12[/tex]
