Question

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. 6b. 9c. 4.5d. 7.5

Explanation:

Step1: Substitute x=3 into equation

Substitute $x=3$ into $y=2.5x - 3$:
$y=2.5\times3 - 3$

Step2: Calculate the result

First compute the product, then subtract:
$y=7.5 - 3=4.5$

Answer:

C. 4.5
