The Slope-intercept form of the equation of the line is:

m: is the slope.
b: the intersection of the line with the y-axis.
The equation of the line
has:

If both lines are parallel, then their slopes are equal. So the slope of the other line is:

To find "b", substitute the given point and the slope into
and solve for "b":

Then the equation of this line is:

Answer:
