Final answer:

To find three additional points through which the given line passes, use the point (4, 2) and the slope m of the line. The correct answer is b. (3, 6), (2, 8), (1, 10).

Step-by-step explanation:

To find three additional points through which the line passes, we can use the given point (4, 2) and the slope of the line. Let's use the slope-intercept form of a linear equation, y = mx + b, where m is the slope and b is the y-intercept.

1. Substitute the given point into the equation to find b. We have 2 = m * 4 + b.

2. Now that we have the values of m and b, we can substitute them into the equation to find the y-values for the three additional points. For example, if we choose (6, 3), we substitute 6 for x and solve for y: y = mx + b = m * 6 + b.

The process of addition follows these basic rules:

Commutative property: Changing the order of addends doesn't change the sum. For example:

5

+

3

=

3

+

5

=

8

5+3=3+5=8.

Associative property: Changing the grouping of numbers being added doesn't change the sum. For example:

(

2

+

3

)

+

4

=

2

+

(

3

+

4

)

=

9

(2+3)+4=2+(3+4)=9.

Identity property: Adding zero to any number doesn't change the value of the number. For example:

5

+

0

=

5

5+0=5.

Inverse property: The sum of a number and its additive inverse (negative counterpart) is always zero. For example:

5

+

(

5

)

=

0

5+(−5)=0.
