which answer is the best estimate of the residual value when x = 1?\n-1.5\n-0.5\n0.5\n1.5

Explanation:

Step1: Recall residual formula

Residual = Observed - Predicted.

Step2: Find observed value at x = 1

From the scatter - plot, when x = 1, the observed y - value is 5.

Step3: Find predicted value at x = 1

Estimate the line of best - fit. When x = 1, the predicted y - value from the line of best - fit is approximately 5.5.

Step4: Calculate residual

Residual = 5 - 5.5=-0.5.

Answer:

-0.5
