-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 linear regression to find a linear function that predicts a student's score on Test B as a function of his or her score on Test A.

A) $y=-19.4-0.930 x$
B) $y=19.4+0.930 x$
C) $y=0.930-19.4 \mathrm{x}$
D) $y=-0.930+19.4 x$
