Line segment AB is drawn between point A(-3, 3) and point B(-1, -1). Work out the gradient of the line segment AB, then find the equation of the graph.
The gradient of segment AB is given by the change in x, over the change in y.m = dy/dx = (y2 -y1)/(x2-x1)y2 = 1y1 = 3x2 = -1x1 = -3m = (-1 - 3)/(-1 -(-3)) = -4/2 = -2Gradient is -2.
