WebMar 17, 2024 · The estimated slope is a combination of two estimated parameters, -24.6 and 2.6: \[-24.6X + 2.6X(12)\] These parameters have estimated variances in the 2nd and 4th positions on the diagonal of the model variance-covariance matrix, which can be viewed with the vcov() function. WebThe greater the magnitude of the slope, the steeper the line and the greater the rate of change. By examining the equation of a line, you quickly can discern its slope and y-intercept (where the line crosses the y-axis). The slope is positive 5. When x increases by 1, y increases by 5. The y-intercept is 2. The slope is negative 0.4.
