consider the graph of the line of best fit, $y = 0.5x + 1$, and the given data points.\nwhich is the residual value when $x = 2$\n- $-2$\n- $-1$\n- $1$\n- $2$
Answer
Explanation:
Step1: Find observed y at x=2
From the graph, when $x=2$, the observed $y$-value is $1$.
Step2: Calculate predicted y at x=2
Substitute $x=2$ into $y=0.5x+1$: $y = 0.5(2) + 1 = 1 + 1 = 2$
Step3: Compute residual value
Residual = Observed $y$ - Predicted $y$ $1 - 2 = -1$
Answer:
-1
