Question

tamikas math teacher plots student grades on their weekly quizzes against the number of hours they say they study on the pair of coordinate axes and then draws the line of best fit. what is the meaning of the $x$-value on the line when $y = 100$?

Explanation:

In a scatter - plot with a line of best fit, the \(x\) - axis represents the independent variable (time spent on homework per week) and the \(y\) - axis represents the dependent variable (quiz score). When \(y = 100\) (a perfect quiz score), the corresponding \(x\) - value on the line of best fit estimates the number of hours a student would need to study per week to achieve that score.

Answer:

The \(x\) - value represents the estimated number of hours a student should study per week to get a quiz score of 100.
