Answer:
2: C
Step-by-step explanation:
To get the residual value, we have to subtract the predicted value from the real value
The predicted value is the one we get through the line of best fit
In this case, we have this as;
y = 0.25(4) + 12
y = 1 + 12 = 13
The real value as it can be seen is 15
So the difference between the values would be;
15-13 = 2
