If the line of best fit is y = 1.18x + 5.4, what is the residual value for the coordinate (4, 9)? 0.86 −0.86 1.12 −1.12

Vocaloid:

residual = actual value - predicted value for the coordinate (4,9), the actual y value is 9. to find the predicted y-value plug in x = 4 into the line of best fit equation. finally, calculate actual value - predicted value to get the residual.
