In order to plot the point P(-2,3,5) in a 3-dimensinal graph, first choose your axes in the three dimensional coordinate system (for simplicity, take a right handed coordinate system as shown in the attached figure). For the point (-2,3,5) notice that x=-2, y=3 and z=5. First, consider the point (-2,3) in two dimensions and locate it in the xy plane (it is shown as a bold cross in the figure). Now travel 5 units in the positive Z-direction above that point to obtain your desired point P. Mark it as P(-2,3,5). It is represented as a bold circle in the figure.
