3. The slope is the vertical change divided by the horizontal change.

A hyperbola is of form
(x-h)^2/a^2 - (y-k)^2/b^2 = 1
the x^2 and y^2 tell you that it is quadratic

Change in position / change in time is measured in meters/second or miles per hour or some other unit of velocity

Yes, area under velocity versus time is position. This is the opposite of the last question.
