Slope of original line = (y2 - y1) / (x2 - x1)
Slope of changed line = (y4 - y3) / (x4 - x3)
Y-intercept of original line = y1
Y-intercept of changed line = y3
Direction of original line = if((y2 - y1) / (x2 - x1) > 0, 'Upward (positive slope)', 'Downward (negative slope)')
Direction of changed line = if((y4 - y3) / (x4 - x3) > 0, 'Upward (positive slope)', 'Downward (negative slope)')
