- Subtraction can be thought of as the inverse operation of addition, OR as addition itself, if you look at it as adding a negative number.

- The number line allows us to interpret subtraction (or addition of a negative) geometrically; we can view it as a movement to the left on the number line with a distance equal to the number being subtracted.

- Lastly, the value of any expression a - b (where a and b are real numbers) is determined by the relative sizes of the numbers. If a > b, then a - b > 0 (a positive result). If b > a, then a - b < 0 (a negative result.

Which of the following is a solution of y - x &lt; -3?
Mariulka [41]

Answer:

Option A. (6,2)

Step-by-step explanation:

We have the following inequality:

y- x

Solving for y we have:

y

The line that limits the region of inequality is

y = x-3

Then the region of inequality are all values of y that are less than f (x) = x-3

In other words, the points belonging to the inequality are all those that lie below the line.

To find out which point belongs to this region substitute inequality and observe if it is satisfied

A. (6,2)

2

2   <em> is satisfied</em>

B. (2, 6)

6

6   <em>it is not satisfied</em>

C. (2, -1)

-1

-1 it is not satisfied

<em>The answer is the option A</em>
