Ответ:
Alternative D is correct
Step-by-step explanation:
As the number of hours worked increases by 1 hour, the amount of tip money earned increases by 10 dollars. The value 10 is simply the slope of the line of best fit which is calculated as; the change in y/the change in x. Using the two points on the line, we calculate the slope as ; (80-20)/(8-2) =10. The slope measures the change in the y-variable for every unit change in x.
