Answer 1

Hey there,

Your question states: Which best models a line?

Your correct answer would be: stick.

Your answer would be stick because a stick is a perfect example of a line. A floor does not and neither a jump rope.

Answer 2

a stick would be best model following are the reasons
1. a floor would not be straight as some of them are elevated or lowered, most of them possess irregularities in their shape
2. pebble can't be taken as a model of line as they don't appear like a line
3. a jump rope might change its shape due to flexibility and elasticity but we assume line as rigid thus stick would be best model
