the value, v, of a shopkeeper's inventory software program is given by v=1/2t+3.
Where t is the number of years since the shopkeeper bought the program. What is the program worth 6 years after it is first purchased?
Plot the point with the given tvalue, 6.

to get this, you just substitute t=6 to the given equation:
v = (1/2)t + 3
v = (1/2)*6 + 3
v = 3 + 3
v = 0
