The vertical axis on a graph is the y-axis and the horizontal axis is the x-axis. Keeping this in mind, if they have the same y coordinate that means vertically they are on the same level but their x coordinates are opposite each other, this means 2 things:
1. they are not on the same level horizontally
2. you have to cross the vertical (y) axis to get from one point to the other.
So to answer your question, These two points are reflected across the y axis.
Hope this helps.
The table on the left is <u>arithmetic</u>
This is because each term is increasing by the same amount (2) each time.
- 3+2 = 5
- 5+2 = 7
- 7+2 = 9
- 9+2 = 11
--------------------------------------------
The table on the right is <u>geometric</u>
Why? Because this time we are multiplying each term by the same value (2) to get the next term.
- 3*2 = 6
- 6*2 = 12
- 12*2 = 24
- 24*2 = 48
Both involve the number 2, but the first table uses addition while the second table uses multiplication.
5/6 - x = 8/15
5/6 - 8/15 = x
25/30 - 16/30 = x
9/30 reduces to 3/10 = x <==Armand burned 3/10 of a row
It would be the second choice. Add by 25.
