First-time poster here.

A little cat, Bella, walks in a straight line, which we shall call the x axis, with the positive direction to the right. As an observant scientist, you make measurements of her motion and construct a graph of the little feline's velocity as a function of time.

Find the x component of Bella's velocity at t = 2.00 s. (in m/s)

Find the x component of Bella's velocity at t = 7.00 s. (m/s)

What is the x component of her acceleration at t = 2.00 s? (in m/s^2)

What is the x component of her acceleration at t = 6.00 s? (m/s^2)

What is the x component of her acceleration at t = 7.00 s? (m/s^2)

For some reason, I can't get the image to show up. Here is the link to it: http://img32.imageshack.us/img32/4815/1012297.jpg [Broken]

v = [tex]\Delta[/tex] x/ [tex]\Delta[/tex] t

a = [tex]\Delta[/tex] v/ [tex]\Delta[/tex] t

The graph is velocity versus time with a negative slope, and the slope is the acceleration. I have no clue as to how I should go about finding the x-component of the velocity in m/s. There's no angle given, only the graph. As for the acceleration questions, I found the the slope of the change in velocity over the time (according to the values on the graph) and the answers were also incorrect. Any hints?
