 Functions Slope (Gradient) of a line The slope (also called: gradient) of a line is the ratio of the change in y compared to the change in x. $slope=/frac{change/;in/;y}{change/;in/;x}$ Look at the picture and find two points P(x 1,x2) and Q(y1,y2) on the line, then determine the slope (gradient) using the following equation: $m=/frac{y_2-y_1}{x_2-x_1}$ The slope (gradient) is m = If you cannot see the pictures, you must install the Plug-in from Java - Click here to download
