When solving a uniform motion problem, how does drawing a diagram of the situation help you

Uniform motion always travel in equal distances in equal intervals of time. So the graph will always be constant.

Once you draw the diagram of a uniform motion, when it comes to plotting points you can easily identify if the points go in a constant rate(uniform) or in  uneven distances(non-uniform).

point a is the center of the circle that passes through points e, f, and g and the center of the circle that passes through points x, y, and z.
