Evan's math teacher finds that there's roughly a linear relationship between the amount of time students spend on their homework and their weekly quiz scores. This relationship can be represented by the equation y=68+6.4x, where y represents the expected quiz score and x represents hours spent on homework that week. What could the number 68 represent in the equation?A student's expected quiz score if they spent 74.4 hours on their homework.The change in expected quiz score for every additional one hour students spend on their homework.A student's expected quiz score if they spent no time on their homework.How many hours a student spends studying all year.

Explanation:

We are given the relationship that relates to the expected quiz score and the number of hours spent on homework that week.

The equation is defined as

[tex]y=68+6.4x[/tex]

For the first part of the question:

We are told to determine what the number 68 represents

From the equation

The number 68 means that the initially expected quiz score (when x =0) of the students is 68.

or the minimum quiz score expected from the students is 68

68 also means the y-intercept of the equation when we plot the equation in a graph
