## hiralpatel121 3 years ago I need help with the attached problem.

1. hiralpatel121

2. sauravshakya

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

3. hiralpatel121

m = slope

4. sauravshakya

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

5. hiralpatel121

-203 = m = slope

6. sauravshakya

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

7. hiralpatel121

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

8. sauravshakya

yep

9. sauravshakya

Now, what do u think V intercept is?

10. hiralpatel121

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

11. sauravshakya

At 1974, t=0

12. sauravshakya

got it?

13. hiralpatel121

Yes. So what would V be then?

14. sauravshakya

9655

15. hiralpatel121

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

16. sauravshakya

Value of Albert Gebra's at 1974

17. hiralpatel121

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

18. sauravshakya

V(t)=0

19. sauravshakya

Now, -203t+9655=0

20. hiralpatel121

So after you solve for t, I get 47.562

21. sauravshakya

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

22. hiralpatel121

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

23. sauravshakya

|dw:1346511852592:dw|

24. sauravshakya

Does it help?

25. hiralpatel121

Yes, but where would I write the equation on the graph?

26. sauravshakya

y=-203x+410377

27. hiralpatel121

Okay. If I have to give the domain and range of the function and then write each of them in interval notation, how would I do that?

28. Chlorophyll

It's first degree equation, so domain ( -inf, inf), also range ( -inf, inf)
