Answer:
hope this helps
Step-by-step explanation:
Angle _1_and angle _4_ are vertical angle pairs.
Angle _4_ and angle _5_ are an alternate interior pair.
Angle _2_ and angle _6_ are alternate exterior pair.
Angle _1_ and angle _2_ are a linear angle pair.
Angle _2_ and angle _7_ are corresponding angle pair.
4 and 2 since 6+2 is 8 and 8 has two factors which are 4 and 2.

Answer:

Step-by-step explanation:
When two lines are parallel means that their slopes are equal. Therefore the line AB will have same slope to a parallel second line,
.
To obtain the slope from the line AB, we need two points, so the general equation will be:

The typical equation of a line is written as y = mx + b
The second line will pass through point (2, -1), so we can substitute:
y2 = mX2 + b
-1 =
(2) + b
then the interception is 
Now to obtain a general equation for the second parallel line will be:
y =
X + b
y =
X -
(2)-1
Finally we get:
y =
(x-2)-1
Answer:
105
Step-by-step explanation:
Substitute X for 7: 3(7)(7-2)
Simplify: 21(5)
Multiply: 105
