Answer 3

you plug in the values for t.. until you reach t=4

when t is one v=3.5
when t is two v=4
when t is three v=4.5
when t is four v=5

Answer 4

make the x=axis be time in years, and the y axis be the value.

Answer 5

The line should have a y-intercept at 3.5

Answer 6

and has a slope of 1/2

Answer 7

so the equation would be y=(x/2)+3.5
