Aline of best fit predicts that when x equals 29 y will equal 27.745 but y actually equals 25 what is the best residual in this case a. -1.255 b. 1.255 c.2.745 d. -2.745 this is a prob and stats question

We know that

the formula in solving residual is shown below:
[Residual value] = [Observed value] - [predicted value]
so
[Observed value]=25
[predicted value]=27.745
[Residual value]=  25 - 27.255> -2.745

Residual values = -2.745

the answer is the option D) -2.745
