**(a) **An object moves in the negative direction if the velocity is negative. Velocity is negative for graphs 2 and 4. **Do NOT** confuse this with the SLOPE of the velocity graphs, which is negative for Graphs 3 & 4.

Graphs **2** and **4** represent an object moving in the negative direction.

(a) Which graphs represent an object moving in the negative direction?

(b) Which graphs represent an object that is speeding up?

(c) Which graphs represent an object that has a negative acceleration?
