(a) Explain why any straight line in the Cartesian plane can be completely determined by knowing the coordinates of only two distinct points on it.
(b) Consider the equation 3x−2y+6=0. Without actually drawing the graph, decide whether the line represented by this equation will cut the first quadrant of the Cartesian plane. Give a clear reason for your answer based on suitable points or intercepts.
