Two students withheld their scores to determine the strength of the model. using the actual line of best fit equation, predict their scores based on their hours worked. actual line of best fit: y= 4.81x + 17.4 hours (x) | score (y) 15 | ? 9 | ?

The value of y is 89.55 at x=15 and 60.69 at x=9.

Step-by-step explanation:

The equation of best fit line is

where, y is scores of two students after x working hours.

We need to find the score after 15 and 9 hours.

Substitute x=15 in the given equation.

Substitute x=9 in the given equation.

Therefore, the value of y is 89.55 at x=15 and 60.69 at x=9.
