Answer:
That's my slovings for your question
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
Simplifying the expression 8x +7 - 2x + y, by combining like terms is 6x + y + 7
<h3>How to simplify an expression?</h3>
The expression have to be simplified by combining the like terms.
Like terms are terms whose variables (and their exponents such as the 2 in y²) are the same.
Therefore,
8x +7 - 2x + y
The like terms are 8x and 2x . Therefore, lets combine it.
8x - 2x + y + 7
Therefore, the simplified expression is 6x + y + 7
