To find the ordered pair for a point on a graph, you look at two numbers:
1.
The x-coordinate: How far right the point is from the start (0). You find this by looking at the bottom number line.
2.
The y-coordinate: How far up the point is from the start (0). You find this by looking at the side number line.
We write them as $(x, y)$.
Step 1: Find Point A
* Look at Point
A.
* Go straight down to the bottom line. It lines up with the number
2. So, $x = 2$.
* Go straight across to the left line. It lines up with the number
4. So, $y = 4$.
* The ordered pair is
(2, 4).
Step 2: Find the second point (labeled B)
* Although the letter "B" isn't printed right next to it, there is a second black dot on the graph. In these problems, we usually solve for the points in order (A, then B).
* Look at this second dot.
* Go straight down to the bottom line. It lines up with the number
5. So, $x = 5$.
* Go straight across to the left line. It lines up with the number
3. So, $y = 3$.
* The ordered pair is
(5, 3).
The other spaces (C through H) are blank because there are no other points drawn on the graph.
Final Answer:
A = (2, 4)
B = (5, 3)
