For this case we have that by definition, the equation of a line in the slope-intersection form is given by:

Where:
m: It's the slope
b: It is the cut-off point with the y axis
According to the statement we have the following equation:

The slope is:

By definition, if two lines are parallel then their slopes are equal. Thus, a parallel line will have slope
. Therefore, the equation will be of the form:

In the statement they tell us that
substituting we have:

Answer:
The equation is:
