0. Two lines AB and AC pass through the points A(4, 3), B(6, 0) and A(4, 3), C(-1,0). By forming simultaneous equations using the equation of the line y = mx + c, find the equation of AB and AC. Write each equation in the form ax + by + c = 0, where a, b, c e Z. Show that the point A(4, 3) is on both lines.​
