A graph of position versus time for a certain particle moving along the x-axis is shown in Figure P2.6. Find
the instantaneous velocity at the instants (a) t 5 1.00 s,
(b) t 5 3.00 s, (c) t 5 4.50 s, and (d) t 5 7.50 s.

Make them both to where they have the denominator of 18that makes 3/2 equal 27/18 and 1/9 equal 2/18so now you have  27/18x+5=2/18subtract 5 from the other sideso now you have 27/18x+2/18-5then subtract 2/18 from 27/18 to get 25/18x=-5then divide 25/18 by -5 and your answer will be  -5/18
