Parallel lines have equal slopes. Determine the slope of your given line by inspection of the cooefficient on x. Then given that the x-coordinate of the x-intercept is 4, the x-intercept is the point (4,0).
Now that you have a slope and a point, you can use the point-slope form of an equation of a straight line to write the desired equation.
where are the coordinates of the given point and is the given/calculated slope.
Note: It is an error to report an intercept as a number. An intercept is an ordered pair. The x-intercept is a point (a,0) where a is the x-coordinate of the x-intercept and the y-intercept is a point (0,b) where b is the y-coordinate of the y-intercept.
