What is the value of 8 in 281,480,100

Well there are 2 eights first of all... so here.
1. The first eight would be the tenth thousandth 
2. The second 8 would be tenth millionth 

If that is what you mean! (:

Well the 8 between the 2 and 1 is 80,000,000 which would be eighty million and the 8 between the 4 and 0 is 80,000 which would be eighty thousand.

Where the white dots are is where your points should be plotted.a translation is simply just moving something from one place to another. in this case, you would move each plot point of the original shape 2 units up, and 5 units to the left.
