WebGradient and y -intercept method. We can draw a straight line graph of the form y = mx + c using the gradient ( m) and the y -intercept ( c ). We calculate the y -intercept by letting x = 0. This gives us one point (0; c) for drawing the graph and we use the gradient to calculate the second point. The gradient of a line is the measure of steepness. WebThe slope or the gradient of the line can be calculated via, m = - a b = - 3 - 1 = 3 1 = 3. Thus, the slope of the given line is 3. The graph of this straight line would be, The graph …
