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
hundredth. Using this equation, estimate the homework grade, to the
nearest integer, for a student with a test grade of 78.

If its non of them tell me..valerie took a day-trip. she drove from her house for a while and took a coffee break. after her coffee break, she continued driving. after  2  hours of driving after her coffee break, her distance from her house was  210  miles. her average speed during the whole trip was  60  miles per hour. valerie created the equation  y−210=60(x−2)  to represent this situation, where  xx  represents the time in hours from her coffee break and  yy  represents the distance in miles from her house. which graph correctly represents valerie's distance from her house after her coffee break?
