Answer:

B. The two lines are neither parallel nor perpendicular.

Step-by-step explanation:

First, put both lines into the same format. In this example, we're going to use y=mx+b format.

x - 4y = -9

-4y = -x + -9

y = (-x + -9) / -4

y = (x+9)/-4

y = (-1/4)x + (-9/4)

y = 3x - 7

If two lines are parallel, they have the same slope. (ie 4 and 4)

If two lines are perpendicular, one line's slope is the negative reciprocal of the other. (ie 4 and -1/4)

Neither is true here.
