1. You already did it.
2. Table
3. t (years since 1990)
4. n (# of cigarettes sold)
5. (t, n)
6. You can see the distribution of the data pretty neatly. There are also many more advantages including it's easier to calculate standard deviation, easier to see the mean, mode and median, and it's also much easier to just tell the extrema of the dataset by just looking at the scattergram.
I hope this helps you
slope=y2-y1/x2-x1
slope=2-(-1)/1-2
slope=3/-1
slope= -3

Answer:
A=24
Step-by-step explanation:
First, we do the equations in the brackets(2x6) which is 12.
Before that, there is a 1/2 which means dividing whatever is inside the brackets by 2 which then becomes 6.
Then we x4 so the answer is 24.
