You multiply or divide integers just as you do whole numbers, except you must keep track of the signs. To multiply or divide signed integers, always multiply or divide the absolute values and use these rules to determine the sign of the answer.


When you multiply two integers with the same signs, the result is always positive. Just multiply the absolute values and make the answer positive.

Positive x positive = positive
Negative x negative = positive

When you multiply two integers with different signs, the result is always negative. Just multiply the absolute values and make the answer negative.

Positive x negative = negative
Negative x positive = negative

When you divide two integers with the same sign, the result is always positive. Just divide the absolute values and make the answer positive.

Positive ÷ positive = positive
Negative ÷ negative = positive

When you divide two integers with different signs, the result is always negative. Just divide the absolute values and make the answer negative.

Someone explain to me how to get the correct answer
Bingel [31]
Graph : 
slope (rate of change) = (-2 - (-4) / (-2 - (-6) = 2/4 = 1/2
y int = (0,-1)
x int = (2,0)

f(x) = 2x - 2
slope(rate of change) = 2
y int = (0,-2)
x int = (1,0)

greater rate of change : f(x) = 2x - 2.....greater by 1.5
greater y int : graph....greater by 1
greater x int : graph...greater by 1
steeper graph : f(x) = 2x - 2

Effectus [21]

Answer:

The figure is a straight line.

The figure lies in the first and the third quadrants.

Step-by-step explanation:

Take five ordered pairs as (1,1),(2,2),(-1,-1),(-2,-2),(3,3)

Here, the first and second coordinates are equal.

Now, plot these points and connect them.

From the graph, it can be observed that the figure is a straight line.

Also, the figure lies in the first and the third quadrants.
