Solve the problem using your calculator.Two separate tests are designed to measure a student's ability to solve problems. Several students are randomly selected to take both tests and the results are shown below. Use a graphing calculator to model the data with a linear function that predicts a student's score on Test B as a function of his or her score on Test A.
A. y = 0.930 - 19.4x B. y = -0.930 + 19.4x C. y = -19.4 - 0.930x D. y = 19.4 + 0.930x
