Option C
Step-by-step explanation:

Problem: 2/7 (4+c)=6
1. 7/2 x 2/7 x (4+c)=7/2 x 6
2. 4+c=7 x 3
3. 4+c=21
4. c=21-4
Answer: c=17

C) 0 < -4 False
Answer:
Step-by-step explanation:
In order to write the equation of this line, we need to pick 2 points on the graph where the line goes right through the intersection of the grids. Actually, you only need 1 of these, because the line goes through at (0, 15). Another point then can be (6, 6). Locate this point so you know what I means when I say that the line goes right through where the grids intersect at x = 6 and y = 6 (as opposed to somewhere in the middle of one of these grids). Find the slope between these 2 points:

Since there's only one choice with that slope, that is the choice you want.
Please find some specific examples of functions for which you want to find vert. or horiz. asy. and their equations. This is a broad topic.
Very generally, vert. asy. connect only to rational functions; if the function becomes undef. at any particular x-value, that x-value, written as x = c, is the equation of one vertical asy.
Very generally, horiz. asy. pertain to the behavior of functions as x grows increasingly large (and so are often associated with rational functions). To find them, we take limits of the functions, letting x grow large hypothetically, and see what happens to the function. Very often you end up with the equation of a horiz. line, your horiz. asy., which the graph usually (but not always) does not cross.
