Question

4. Grant and Pedro are comparing theirstocks for the week. On Monday, theirresults were opposites. Explain how youwould graph their results for Monday ifGrant lost $4.Grant's point is 4 units to the rightof 0 on a number line, and Pedro'spoint is 4 units to the left of o.B Grant's point is 4 units to the rightof 0 on a number line, and Pedro'spoint is the same point.Grant's loss is a point 4 units tothe left of 0 on a number line, andPedro's point is 4 units to the rightof 0.D Grant's loss is a point 4 units tothe left of 0 on a number line, andPedro's point is the same pointbecause it's already negative.

Answer 1

Grant and Pedro have opposite results: if one of them has a result such as x the other will have -x, for instance.

We have that Grant lost $4 on Monday. It can be expressed as -$4. Then, Pedro won $4 (or +4$) on Monday.

Then, to graph this result, we need to know that at the right of zero, in the number line, are positive numbers. On the contrary, at the left of zero, we represent the negative numbers.

Therefore, to graph these results for Monday:

Grant: -$4

Pedro; +$4

Grant's point is 4 units to the left of 0.

Pedro's point is 4 units to the right of 0.

In this way, the correct option is C:

Grant's loss is a point 4 units to the left of 0 on a number line, and Pedro's point is 4 units to the right of 0.
