WebApr 20, 2015 · 1 Answer. A graph shows direct variation if it goes through the origin, (0,0). The equation is y = kx, where k is a constant, which is apparent when we write the equation as y x = k. In slope-intercept form, the equation would be y = mx +b, where m = k, and b = 0. Lets suppose that k = m = 2. WebWhen an equation that represents direct variation is graphed in the Cartesian Plane, it is always a straight line passing through the origin. Think of it as the Slope-Intercept Form of a line written as. y = mx + b y = mx + b where b = 0 b = 0.
