WebThe gradient is the inclination of a line. The gradient is often referred to as the slope (m) of the line. The gradient or slope of a line inclined at an angle θ θ is equal to the tangent of the angle θ θ. m = tanθ m = t a n θ. The gradient can be calculated geometrically for any two points (x1,y1) ( x 1, y 1), (x2,y2) ( x 2, y 2) on a line.
