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 43
