WebHow Do You Find the Gradient Using the Equation of the Line y = mx + c? In the equation y = mx + c, the coefficient of x represents the gradient of the line. This gradient of the line is the 'm' value, in the equation y = mx + c. The value of m can be calculated from the angle which this line makes with the x-axis or a line parallel to the x-axis.
