Blood pressure: A blood pressure measurement consists of two numbers: the systolic pressure, which is the maximum pressure taken when the heart is contracting, and the diastolic pressure, which is the minimum pressure taken at the beginning of the heartbeat. Blood pressures were measured, in millimeters of mercury, for a sample of 7 adults. The following table presents the results. Systolic Diastolic 116 70 107 71 105 66 113 77 118 88 133 91 110 74   Use the TI-84 calculator. Compute the least-squares regression line for predicting diastolic pressure (y) from systolic pressure (x). Round the slope and y-intercept values to at least four decimal places.
