I have a line of best fit problem...

Question

Sam surveyed a total of 10 students to see how many tests and quizzes in the last month. Through her line of best fit line, she figured out that the equation of the line is y=0.36x+0.27.

She added a point representing her quizzes and tests. She had 12 quizzes. When she added her point, her line of of best fit and slope decreased. What is the maximum number of test Amanda could have had in the last month?

Gordon,
