The points A, B, C, and D are plotted on the number line below.
Let x represent the expression A + C - (D + B).
Let y represent the expression -A - (-C) - (D - B).
Based on the given points A, B, C, and D being plotted on the number line, we can represent their positions as follows:
A B C D
Now, let's substitute the corresponding values into the expressions x and y:
x = A + C - (D + B)
y = -A - (-C) - (D - B)
Therefore, we can represent the values of x and y using the given expressions and the positions of A, B, C, and D on the number line.
