Find the coordinates of the point where the line passing through the points (3, 4, 1) and (5, 1, 6) cuts the y - z plane. |

Answer» y - z plan is x = 0 ...(i) the eqn. of the line through the point (5, 1, 6) and (3, 4, 1) is (x - 5)/(3 - 5) = (y - 1)/(4 - 1) = (z - 6)/(1 - 6) (x - 5)/-2 = (y - 1)/3 = (z - 6)/-5 ...(ii) Any point an through line is(5 - 2h,1 + 3h,6 - h) Thus f = 8/2 The required point of intersection of plane (i) and two line (ii) is (0,17/2,-13/2) |
