20pointsa teacher takes the semester exam scores for the first semester of a course and designs a line of best fit to predict the semester exam scores for the second semester, y , based on the number of days of attendance, x . her equation for the line of best fit is y=0.7x+37 . select the test score that the teacher should expect from a student who did not attend her course.4.4440.737

Solution: The test score that the teacher should expect from a student who did not attend her course is 37.

Explanation:

The teacher's equation for the line of best fit is

We know the equation for the line of the best fit is:

Where:

is slope of the equation. It represents the rate of change in y as one unit change in x.

is the intercept. It represents the expected mean value of y when all x=0.

Therefore, in the given teacher's equation, the slope is 0.7 and intercept is 37.

Here the intercept means the average score of student who who did not attend her course.

Therefore, the test score that the teacher should expect from a student who did not attend her course is 37.
