Question

v=-1/2t+4  //  i need step by step breakdown so i can graph and the worth of this after 4years

Answer 1

v=-½t+4, where v=value and t=time in years.

Initially the value is 4 (t=0).

After 4 years the value is v=-2+4=2.

You have two points here (0,4) and (4,2). Draw a line starting at (0,4) and passing through (4,2).

t is the horizontal axis and v the vertical axis.
