Question

Draw a right -handed rectangular reference frame with axes ranges x = -5 to +5, y = -5 to +10 , z = -5 to +5. Sketch the following planes on your reference frame. X-y plane passing through z =5, y-z plane passing through x = -2, z-x plane passing through y =8. What are the cartesian co ordinates of the point at which the three planes all meet?

Answer 1

since you have only provided a single value for each coordinate, and the planes are all perpendicular to an axis, the intersection must clearly be (-2,8,5).
