Step-by-step explanation:

the table shows the test scores and the sleep averages of several students.

Test Score (%) 88 75 76 92 96 94 83 90 99 65 77 88 82 83 94 97

Average Sleep (h) 7 6.5 6 7.5 8 7 6.5 8 8.5 5 7 9 8 8.5 8.5 9

(a) Write the least squares regression equation that models the data.

Let x = the test score and y = average sleep.

(b) Use the equation to determine the approximate test score of a student who sleeps an average of 8 hours a night.

step-by-step explanation:

from this example, we can see that subtracting with integers is the same as adding the opposite. we can solve using a number line or by using the saying "keep, change, change" to us solve. it is important to remember that we can subtract a negative and end up with a larger number than we started with.
