The velocity of a car changes over 7s time period ,as show in the following table
position (m) 0 2 4 6 8 10 12 12
time (s) 0 1 2 3 4 5 6 7

a. port : the displacement-time graph of the motion
b. what is the displacement of the car during the entire 7s
c. find the slop of the line between t=0s and t=4.5swhat does this slop represent
d. find the slop of the line between t=6s and 7s​
