(-3,-4) and its y-intercept is (0,9).
This line has slope 13/3.
[(9- (-4)]/[0 -(-3)]= 13/3
Parallel lines have the same slope.

line that is parallel to the first line and passes through the point (3,-7)?

y = (13/3) x - 20 --> Answer (not a given option)

@2012D

> y = (13/3) x - 20  is the correct answer but is not one of the options listed by the OP.

You have to simplify

so what's the answer?

the question was wrong it was supposed to be (0,-9) not (0,9). I still dont understand how to come up with te answer though. :(
