Question

question 6 of 10
a set of data points has a line of best fit of $y=2.5x - 1.5$.
what is the residual for the point (5,12)?
a. 11
b. 12
c. -1
d. 1

Explanation:

Step1: Calculate predicted y-value

Substitute $x=5$ into $y=2.5x-1.5$:
$y = 2.5(5) - 1.5 = 12.5 - 1.5 = 11$

Step2: Compute residual (actual - predicted)

Residual = $12 - 11$

Answer:

C. -1
