( x )	given	predicted	residual
2	3	4	-1
3	8	7	1
4	9	10	?

-1
1
3

Explanation:

Step1: Recall the formula for residual

Residual = Given - Predicted.

Step2: Substitute the values for \(x = 4\)

Given \(y\) value is \(9\), predicted \(y\) value is \(10\). So, Residual \(=9 - 10\).

Step3: Calculate the result

\(9-10=-1\).

Answer:

-1 (corresponding to the option \(-1\))
