Question

I need help with the attached problem.

Answer 1

In y=mx+c can u tell me what is the slope?

Answer 2

m = slope

Answer 3

So, V(t)=-203t+9655........ what do u think is the slope

Answer 4

-203 = m = slope

Answer 5

Now, since slope is negative it means it is decreasing at the rate of 203 per year

Answer 6

So the value of the Gremlin is decreasing at the rate of 203 per year?

Answer 7

yep

Answer 8

Now, what do u think V intercept is?

Answer 9

V represents the value in year t. So, in 1974, V(1974) = -203(1974)+9655

Answer 10

At 1974, t=0

Answer 11

got it?

Answer 12

Yes. So what would V be then?

Answer 13

9655

Answer 14

Okay. And what would be the meaning of the V-intercept in this application?

Answer 15

Value of Albert Gebra's at 1974

Answer 16

Okay, thanks. Now I have to find the t-intercept for the application and explain what this means in terms of the application.

Answer 17

V(t)=0

Answer 18

Now, -203t+9655=0

Answer 19

So after you solve for t, I get 47.562

Answer 20

It represents after 47.562 years the Albert ... value will be zero

Answer 21

Okay. And if I have to sketch a graph of the function, labeling the axis, scale and equation, how would I do that?
