You do not. You see it stereoscopically, but the brain compares the images with experience and assumes threedimensional interpretations. This can be used to fool people with optical illusions. Forms that are possible in a twodimensional world, but does not have a representation in 3D that makes sense.
Assuming it is a spped v/s time graph, a horizontal line represents motion at a constant speed.
1) Separate the vectors into components (if they are not already expressed as components). 2) Add each of the components separately. 3) If required, convert the vectors back to some other form. For twodimensional vectors, that would polar form.
A straight slanted slope on a velocity-time graph indicates that the object is moving with a constant acceleration.
