A mathematics teacher wanted to see the correlation between test scores and homework. The homework grade (x) and test grade (y) are given in the accompanying table. Write the linear regression equation that represents this set of data, rounding all coefficients to the nearest tenth. Using this equation, estimate the homework grade, to the nearest integer, for a student with a test grade of 74.
Homework Grade (x) Test Grade (y)
8585 9090
7676 6767
8787 7979
5454 5454
7272 6868
8686 7373
7474 7575
7878 6363
