Slope of a line in coordinates system, from f(x)=-12x+2 to f(x)=12x+2. The slope of a line in the plane containing the x and y axes is generally represented by the letter m, and is defined as the change in the y coordinate divided by the corresponding change in the x coordinate, between two distinct points on the line.ere the slope of the road between the two points is simply described as the ratio of the altitude change to the horizontal distance between any two points on the line.
