Then graph the equation and use the graph to determine the value of Bob’s coin collection if it is 9 years old.

Please show all of your work.

**Jai**, Tuesday, November 1, 2011 at 5:12amv = (1/3)t + 12

to plot this, the easiest way (for me) is to get the x- and y-intercept (in this case, the x-axis = t-axis, and y-axis = v-axis).

to get t-intercept, we let v = 0 and solve for t:

v = (1/3)t + 12

0 = (1/3)t + 12

-(1/3)t = 12

t = -36

thus t-intercept is at (-36, 0)

to get v-intercept, we let t = 0 and solve for v:

v = (1/3)t + 12

v = 12

thus v-intercept is at (0, 12).

to plot, locate these points. connect them, and extend on both ends. you must plot this accurately since you need to find the value of v at t = 9.

hope this helps~ :)
