Answer:
C and E
Step-by-step explanation:
To answer this question, we plug in the X values of the coordinates into the equation to see if they'll give us the corresponding Y value.
(X, Y)
Example:
Y = 5X
6 != 5 * 3
We do this for every coordinate point. If the problem doesn't make sense, it doesn't fall on the line. Let's test every one of these.
B. (0, 1)
1 != 5 * 0
C. (3, 15)
15 = 5 * 3
D. (4, 2)
2 != 5 * 4
E. (-1, -5)
-5 = 5 * -1
F. (-1, 5)
5 != 5 * -1
* For those who don't know, the != is how to say "not equal to" in computer science.

You can tell this by "these are parallel lines"
Answer:
From Online Buying is more suitable
The difference between per diaper price is $0.04
Step-by-step explanation:
Given:
56 diapers can be bought for $ 28
and
online 112 diapers for $ 52
TO find:
Better deal = ?
Per diaper save= ?
Solution:
Let the first type be x
Now for x
Price of 56 diapers are $ 28
Price of one diaper =
=$0.5 / diaper
Now for online let it be represented by O
Price of 112 diapers are $52
Price of one diaper =
=$0.46 / diaper
Price of one diaper from online is less then price of one diaper from we bought not online
Difference of per diaper price = 0.5 - 0.46
=$0.04
So buying diapers from online would be suitable
