Question

Reda needs to graph -31,-22,-17,+41 and +111 on a number line. She plans to use an interval of 1 because several of the numbers end in 1. Is this a good choice? Explain why or why not.

Answer 1

Not so good because the range is 142 -- it would require making 140+ "tic marks."
So better would be to use maybe a spacing of tic marks by 10s and then placing the points carefully between the marks.

Answer 2

you mean like no

Answer 3

No, it is not a good choice.
since it's the values are larger.
