Test Your Knowledge: What are the X and Y Axes?

📚 Quick Study Guide

• 📈 The X-axis is the horizontal line on a graph. It represents the independent variable.
• 📉 The Y-axis is the vertical line on a graph. It represents the dependent variable.
• 📍 The point where the X and Y axes intersect is called the origin. Its coordinates are (0, 0).
• ➕ Points on a graph are represented as ordered pairs (x, y), where x is the value on the X-axis and y is the value on the Y-axis.
• 🧭 Moving right along the X-axis increases the x-value. Moving left decreases it.
• ⬆️ Moving up along the Y-axis increases the y-value. Moving down decreases it.
• 📐 The X and Y axes divide the coordinate plane into four quadrants.
