Answer:
B. & E.
Step-by-step explanation:
First, to find your slope, put your line into slope-intercept form.


Your slope is
.
Now, you can find the y-intercept of your parallel line by plugging your given point and your slope into point-slope form.

Your y-intercept is 1.
If you notice, answer choice E is equivalent to one of our steps in converting it to point-slope form. Therefore, E is one of your answers.
The equation of your parallel line is:

B is also a correct answer.
If you put B into slope-intercept form, you get the following:

This, of course, is equivalent to the parallel line which we already found, so we know it is parallel.
