Answer:
a = –0.4 and b = 0.15
Explanation:
<em>Shanti wrote the predicted values for a data set using the line of best fit y = 2.55x – 3.15. She computed two of the residual values. What are the values of a and b?</em>
<em />
Residual values are the difference between Given and predicted value. That is:
Residual Value = Given - Predicted
Taking the values of the table:
a = 4.1 - 4.5 = -0.4
a = -0.4
And b is:
b = 7.2 - 7.05 = 0.15
b = 0.15
That means right answer is:
<h3>a = –0.4 and b = 0.15</h3>
