The point is
and the equation of line is
.
Rewrite the equation
in the slope - intercept form by solving for y.
Divide each side by 2.
\

The equation
is in the form
where m is slope and b is y - intercept.
Therefore slope of given line is 2.
\If two lines are parallel, then they have the same slope.
\So, the parallel line through
has a slope of 2.
To find the y - intercept, substitute the values of
in the slope - intercept from of equation
and solve for b.


Add 4 to each side.
