There's no previous equation that proves your answer. That is, we don't know if the equation is more than first degree :-) Also in parabola graph, the value of x (roots) in a given second or more degree equation determines the x-intercepts, not the slope or vertex/vertices that show the curve/s and the minimum (opens upward) or maximum (opens downward), depending on the sign of the coefficient of the leading term :-)
