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.
Given inequality is:

Now for (6,-4), Put x=6 nd y=-4 in given inequality:

So for (6,-4) this inequality is true.
For (-2,-3) put x=-2 and y=-3 in given inequality:

As -32 is less than -8 then this condition is also true.
simillarly you can check for other options also.
For (-7,5) Put x=-7 and y=5 in given inequality:

As 12 is grater than -8 so this condition is false.
And for (-6,0) put x=-6 and y=0 in given inequality:

As -24 is less than -8 so it is true.
Answer:
Vertical angles are congruent
Step-by-step explanation:
vertical angles intersect, usually forming a X shape, and have to always be equal
