Question

question 4 of 10
a data set consists of the following data points:
$(3, 5), (5, 8), (6, 13)$
the line of best fit has the equation $y=2.5x - 3$. what does this equation predict for a value of $x=3$?
a. 6
b. 9
c. 4.5
d. 7.5

Explanation:

Step1: Substitute x=3 into equation

$y = 2.5(3) - 3$

Step2: Calculate the product

$y = 7.5 - 3$

Step3: Compute the final value

$y = 4.5$

Answer:

C. 4.5
