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

203 = m = slope

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

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

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

At 1974, t=0

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

Now, 203t+9655=0

So after you solve for t, I get 47.562

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

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

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?

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