← The figure shows a blue line parallel to the x-axis through (0, 1, 1) and a red line parallel to the y-axis through (-1, -3, 3), with lengths in metres. A cable car designer needs the shortest distance between the two lines. What is it?A flat plate passes through the point (1, 2, 3) and a rod fixed at that point stands at right angles to the plate. The rod points along î + ĵ + k̂. Which is the equation of the plate? →
