2. Line Representation (10 marks) (a) (3 marks) Given two points defining a line segment: PO = (x, y) = (1.1) P1 = (x1, y1) - (5.3) Write the line equation in parametric form: P(a) (in vector form) and xa) = (in separate forms for x and y coordinates) y(a) (b) (3 marks) Given another two points defining a line segment: P3 = (x3, y) = (2,5) P4 = (x, y) = (3.3) Write the line equation in parametric form (in vector form) Pa) and xa) in separate forms for x and y coordinates) ya) - (3 marks) Compute the intersection point between the two lines. (d) (1 mark) is the intersection point between P1 and P2
