Y COORDINATE
Definition Of Y-Coordinate
The second number in an ordered pair is the y-coordinate.
Examples of Y Coordinate
In the ordered pair (2, 4), the y-coordinate is 4
In the ordered pair (1, - 7), the y-coordinate is - 7
To reach the point (1, 3), move 1 unit to the left from the origin and then 3 units up

Solved Example on y-coordinate
Ques: Which of the points has 2 as the y-coordinate?
Choices:
A. A
B. B
C. C
D. D
Correct Answer: B
Solution:
Step 1: The ordered pair for the point A is (- 2, 4). So, A has 4 as the y-coordinate
Step 2: The ordered pair for the point B is (2, 2). So, B has 2 as the y-coordinate
Step 3: The ordered pair for the point C is (3, - 2). So, C has - 2 as the y-coordinate
Step 4: The ordered pair for the point D is (- 2, - 1). So, D has -1 as the y-coordinate
Step 5: So, the point B has 2 as the y-coordinate.
Quick Summary
- The y-coordinate represents the vertical position of a point.
- It is the second value in an ordered pair (x, y).
- Positive y-coordinates are above the x-axis, and negative y-coordinates are below.
🍎 Teacher Insights
Use graph paper to help students visualize the coordinates. Start with simple examples and gradually increase complexity. Relate the concept to real-world scenarios, such as mapping locations.🎓 Prerequisites
