Answer

Explanation:

Step1: Find predicted value

When $x = 3$, substitute into $y = 1.6x-4$. So $y_{predicted}=1.6\times3 - 4=4.8 - 4 = 0.8$.

Step2: Find actual value

From the table, when $x = 3$, $y_{actual}=-1$.

Step3: Calculate residual

Residual = $y_{actual}-y_{predicted}$. So residual $=-1 - 0.8=-1.8$.

Answer:

$-1.8$
