Find parametric equations for the line. (Use the parameter t.) The line through the origin and the point (4, 7, -1) (x(t), y(t), z(t)) = Find the symmetric equations. X 4 = 2/7 = 2 =27=2 x - 4 = y - 7 = z + 1 104 = 2 = - x + 4 = y +7=z-1 = -2 Find parametric equations for the line. (Use the parameter t.) The line through the points (0,1,1) and (8, 1, -9) (x(t), y(t), z(t)) = Find the symmetric equations. Z +9 - 10 65 X-8 8 X+9 Find parametric equations and symmetric equations for the line. (Use the parameter t.) The line through (1, 1, 0) and perpendicular to both i + j and j + k (x(t), y(t), z(t)) = ([ The symmetric equations are given by x + 1 = (y + 1) = 2. -(x - 1) = y 1 = z. x 1 = -(y - x = 1 = y 1 = -z. x + 1 = (y + 1), z = 0. 1) = z.
