Now, first, calculate the intercept and slope for the regression. Calculation of Intercept is as follows, a = ( 628.33 * 88,017.46 ) – ( 519.89 * 106,206.14 ) / 5*

Regression Line Formula = Y = a + b * X Y = 59.98 + 0.59 * X Y = 105.15 ~ 105 Therefore, as per the regression level, the glucose level of a 77
