y=5/3x
this is because f(x)=x is one of (identity function) the 12 basic functions and when you multiply it it will shift it on the y axis
If you were to do y=x+5/3 it would make a horizontal shift to the left 5/3
So the unit your on is mostly about knowing the number located in the function that will make the graph shift different ways
D≈2π(6371-1737.5)
d≈9267π
d≈29113.1km (to nearest tenth of a kilometer)
1000000000 because less than this number is 9 digits and more than this numbet is not least
