(a) Show that the parametric equations x = x1 + (x2 − x1)t, y = y1 + (y2 − y1)t where 0 ≤ t ≤ 1, describe the line segment that joins the points P1(x1, y1) and P2(x2, y2). This answer has not been graded yet. (b) Find parametric equations to represent the line segment from (−2, 8) to (3, −2). (Enter your answer as a comma-separated list of equations. Let x and y be in term
