Answer:
1). y = -4/7x         2). y = 7/4x - 65/4
Step-by-step explanation:
1). When a line is parallel, the slope remains the same. 
y = -4/7x + b
-4 = -4/7(7) + b
-4 = -4 + b
0 = b 
The equation is simply y = -4/7x. 
2). When a line is perpendicular, the slope becomes the exact opposite.
y = 7/4x + b
-4 = 7/4(7) + b
-4 = 49/4 + b
-65/4 = b
The equation is y = 7/4x - 65/4.

Check the picture below.
notice the solid circle at -4 and 3, since it includes those points.
also notice the dashed line, though the lines keeps on going those ways, is not included in the piece-wise, since it's not part fo the domain or constraints.
