www.csecmathtutor.comCalculate the gradient of a straight line given two pairs of coordinates ,,y 2 To determine the gradient of line AB we need to examine the ratio of the change in the y - distance compared with the change in the x – distance.We call the change in y the rise and the change in x the run. This can be written down as
