Find parametric equations to represent the line segment from (-2, 3) to (13, -9).
a) x = -2 - 15t; y = 3 - 12t; for 0 <= t <= 1
b) x = -2 - 15t; y = 3 - 12t; for 0 <= t <= 2
c) x = 9 - 15t; y = 3 - 12t; for 0 <= t <= 2
d) x = -2 + 15t; y = 3 - 12t; for 0 <= t <= 1
e) x = 2 + 15t; y = 3 - 12t; for 0 <= t <= 1
