B) If the line is parallel, that means the slope is the same.
The slope for the original line is
= 
.
The second form of coral line would be y = -1/4x + (any number). You could use y = -1/4x + 3.
c) Solve 12x = 24 + 3y for y.
3y = 12x - 24
y = 4x - 8
Perpendicular lines have negative reciprocal slopes... the negative reciprocal for -1/4 is 4. So yes, the third coral structure is perpendicular to the first coral.

23. Option A: 4p + 175 = 375
24. $50 per monthly payment if the down payment is $175
25. Option C: 28x + 64 = 456

a. See the diagram attached. It was drawn on Google Drawing so obviously not to scale but you get the gist.
b.
Not quite sure what a verbal model is but with the diagram you should be able to describe it.
4 bookshelves, 2 on each side, in an entertainment center and a middle section of 30 inches wide all add up in its entirety to equal 90 inches.
c.
4x + 30 = 90
d.
4x = 60
x = 15
The bookcases are each 15 inches wide
