The line passes through the points
.
Substitute the values of
in the slope formula
.
.
Because the slopes of parallel lines are same, the slope of parallel line through
is
.
To find the y - intercept, substitute the values of
in the slope - intercept from of equation
and solve for b.

.
Substitute the values of
in the slope - intercept form of equation
.
The equation of parallel line is
.
The option A is correct answer.
