A. x and t

B. x and t

^{2}

C. x/t and t

^{2}

D. x/t and t

E. x/t

^{2}and t

This is my approach to the problem:

The initial velocity, u = at.

Hence, the distance traveled by the stone, x = 0.5at

^{2}

x/t

^{2}= (0.5at

^{2})/t

^{2}

= 0.5a

Since a is a constant, then a flat line would be represented in a graph of axes x/t

^{2}and t.

Also, in D., x/t = v, which decreases at a constant rate because of the constant deceleration, so this is another straight-line graph.

Obviously, there must be something wrong with my reasoning because there can only be one, and not two answers for each multiple choice question.
