Homework Help: algebra

Posted by anonymous on Friday, May 13, 2011 at 7:16pm.

The value, v, of a shopkeepers inventory software program is given by v= -1/2t+5, where t is the number of years since the shopkeeper bought the program. What is the program worth four years after it is 1st purchased. Plot the point with the given t-value, 4.

I have made calculations of
-1/2t(0) + 5 = v 5 (0,5)
-1/2t(4) + 5 = v 3 (4,3)
-1/2t(2) + 5 = v 4 (2,4)
-1/2t(8) + 5 = v 1 (8,1)

On the graph I cannot figure out how to plot t4. The only way the lines will go is from 0 on both sides.

Can someone help me with this without a graph to show me?

Thanks so much.
