The lines y=-3x+4 and y=-3x-17 are perpendicular.

No, they are not perpendicular, but they are parallel.

Step-by-step explanation:

1. Identify the Slope of both equations

   The slope of y=-3x+4 is -3

   The slope of y=-3x-17 is -3

2. Determine slopes

   If 2 lines are parallel, they have the same slope

   If 2 lines are perpendicular, their slopes are opposite reciprocals.

        e.g. The opposite reciprocal of 7 is -1/7

3. Determine if slopes are parallel or perpendicular

   Since the slop of both lines is -3, the two lines will be parallel to one     another with different points intersecting at the y-axis (4 and -17)
