Answer:
8x+1
Step-by-step explanation:
4(x-1) + (x+2) + 3(x+1)
4x-4 + x+2 + 3x+3
combine all x
4x+x+3x= 8x
combine all numbers without variables
(-4) + 2+3=1
8x+1

Answer:
<h2>y = 3x + b where b is any real number</h2>
Step-by-step explanation:
The slope-intercept form of an equation of a line:

m - slope
b - y-intercept
We have the equation: 
Parallel lines have the same slope. Therefore the equation of the lines that are parallel to the given line if in form:

where b is any real number.
