Sam looked at two points that were graphed on a vertical number line. he saw the points −2 and 1.5. he wrote the following description:

"i am looking at a vertical number line that shows the location of two specific points. the first point is a negative number, so it is below zero. the second point is a positive number, so it is above zero. the negative number is −2. the positive number is 1/2 unit more than the negative number."

determine if you agree or disagree with the representation. then, defend your stance by citing specific details in your writing.

The correct statement would be: The positive number is 1/2 unit less than the opposite of the negative number.

Step-by-step explanation:

All stamemts are true except for the last one:

The positive number is 1/2 unit more than the negative number.

We can see in the plot that 1.5 is above zero and -2 is below zero.

So, -2<1.5

The opposite number of -2 is 2 and we can see that opposite number is 1/2 greater than 1.5. So, -2<1.5<2

hello from mrbilldoesmath!

answer:

the domain is the set { -2, 0, 2, 3}

discussion:

the domain is the set of x values in the ordered pairs (x,y). taking the x, or first component, of each ordered pair gives   -2, 0, 2, 3.
