解析
Two approaches that you could use to solve this problem are:
1: Translate from algebra to a number line.
2: Plug in values for the variables.
Approach 1: The following figure represents the information given in the problem on a number line.
On the number line, 1 - y is the distance between 1 and y, and y — x is the distance between y and x. If y is exactly halfway between x and 1, then 1 -y is equal to y -x; and if y is
not
halfway between x and 1, then 1 -y is
not
equal to y - x. But y can be
any
number between x and 1, so the correct answer is Choice D.
Approach 2: Since this problem involves subtraction, it is a good idea to choose values for x and y that are close to each other as well as values that are far apart. For example, if x = 0.4 and y = 0.5, then 1 -y = 0.5 and y - x = 0.1; and if x = 0.1 and y = 0.9, then 1 - y = 0.1 and y - x = 0.8. This shows that the relationship cannot be determined, and the correct answer is Choice D.
