📚 Topic Summary
The X and Y axis are the two main lines that make up a coordinate plane. The X-axis is the horizontal line, and the Y-axis is the vertical line. We use them to locate points using coordinates like (3, 2), where the first number tells us how far to move along the X-axis, and the second number tells us how far to move along the Y-axis. Understanding these axes is key to graphing and solving math problems! Think of it like a map to find hidden treasure 🗺️!
🧮 Part A: Vocabulary

✍️ Part B: Fill in the Blanks
The X and Y axis form a _________ plane. The X-axis is _________ and the Y-axis is _________. The point where they cross is called the _________. To find a point, we use _________ which tell us how far to move along each axis.
(Answers: coordinate, horizontal, vertical, origin, coordinates)
🤔 Part C: Critical Thinking
Imagine you're creating a treasure map. How would you use the X and Y axis to describe where the treasure is buried to your friend?
