Question

a line of best fit is drawn for a scatterplot of study hours vs. test scores. the equation of the line is $y = 12x + 50$. predict the test score of a student who studies for 3 hours. question 9 the scatterplot below shows the relationship between the number of hours a student studies and their test score. describe the overall trend in the data. then, explain where a line of best fit would go and whether there are any outliers or clusters

Explanation:

Step1: Substitute \(x = 3\) into the equation

Given the equation \(y=12x + 50\), when \(x = 3\), we have \(y=12\times3+50\).

Step2: Calculate the value of \(y\)

First, calculate \(12\times3 = 36\). Then, \(y=36 + 50\).
Since \(36+50=86\), we get \(y = 86\).

Answer:

\(86\)
