Answer:
B. 4 [0, 4]
Step-by-step explanation:
The quickest way to do this is to plug the coordinates into the Slope-Intercept Formula instead of the <em>Point-Slope Formula</em>. It does not matter which ordered pair you choose:
-5 = -3[3] + b
-9
4 = b
y = -3x + 4
__________________________________________________________
10 = -3[-2] + b
6
4 = b
y = -3x + 4
** You see? I told you it did not matter which ordered pair you choose because you will always get the exact same result.

Answer
3x6=18 or 3c=18
Step-by-step explanation:
I don't know in what level of mathematics you're in. It depends...
c= cost c=6
X - 3y=0
3y - 6 =2x
__________
x - 3y=0 ........(1)
-2x + 3y=6 ........(2)
__________
-x = 6 ==》x = -6 .........(3) subst. in (2)
-2 (-6) + 3y = 6 ==》3y= -6 ==》y = -2
if one customer shows up, and she buys one song, that's $1.29, if she doesn't buy anymore, then that's the charge.
the first song is always at a full price, and after that, to encourage buying, the next ones are just 99 cents, let's see how it goes after a few songs purchases.
1 song.........................$1.29
2 songs.......................$1.29 + 0.99(2)
3 songs.......................$1.29 + 0.99(3)
4 songs.......................$1.29 + 0.99(4)
c songs.......................$1.29 + 0.99(c)
s(c) = 1.29 + 0.99c.
