To calculate the positional relationship of two lines in a point-sampling linear equation system, you can first determine the slope of each line using the coefficients of the x and y terms in the equations. If the slopes are different, the lines are not parallel. Next, you can find the y-intercepts of the lines by setting x=0 in the equations. If the y-intercepts are different, the lines are not coincident. By analyzing the slopes and y-intercepts, you can determine if the lines are parallel, intersecting at a single point, or coincident. **
