consider the graph of the line of best fit, y = 0.5x + 1, and the given data points. which is the residual value when x = 2? -2 -1 1 2
Answer
Explanation:
Step1: Find predicted value
Substitute $x = 2$ into $y=0.5x + 1$. $y_{predicted}=0.5\times2+1=1 + 1=2$
Step2: Determine actual value from graph
From the graph, when $x = 2$, the actual $y -$value of the data - point is $1$.
Step3: Calculate residual
Residual = Actual value - Predicted value. Residual=$1 - 2=-1$
Answer:
-1
