Question

William's 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. Based on the line of best fit, how much time should someone study to expect a quiz score of 94?

Answer 1

To determine how much time someone should study to expect a quiz score of 94, we need to find the x-coordinate on the line of best fit that corresponds to a y-coordinate of 94.

Step-by-step explanation:

The line of best fit represents the average relationship between the number of hours studied and the quiz score. To determine how much time someone should study to expect a quiz score of 94, we need to find the x-coordinate on the line of best fit that corresponds to a y-coordinate of 94.

If the equation of the line of best fit is y = mx + b, where y is the quiz score, x is the number of hours studied, m is the slope, and b is the y-intercept, we can use the equation to solve for x when y = 94. Plug in 94 for y and solve for x.

Once we find the x-coordinate, we will have the number of hours someone should study to expect a quiz score of 94.
