Question

Lines

m
and
n
are parallel. The equation of line m is =3+3
y
=
3
x
+
3
. What is the equation of line
n
?

Answer 1

Answer y = 3x + b

Explanation:

Answer 2

y = 3x + b

Explanation:

Parallel lines have the same slope.

The slope-intercept form of an equation of a line:

`y=mx+b`

m - slope

b - y-intercept

We have the equation of the line m:

`m:\ y=3x+3\to m=3`

Therefore the equation of a line n parallel to the line m is:

`y=3x+b`

where b is any real number
