The parametric equations X = X1 + (X2 - X1)t, y = y1 + (y2 - y1)t where 0

The parametric equations x = Xl + ("2 - Y = + (Y2 -Yl)t where 0 t 1 describe the line segment that joins the points PI(XI, Yl) and P2(X2, n). Use a graphing device to draw the triangle with vertices A(l, 1), B(3, 3), C(l, 6). Find the parametrization, including endpoints, and sketch to check. (Enter your answers as a comma-separated list of equations. Let x and y be in terms of t.) A to B B to C A to C
