Test Your Knowledge: Distance Formula Questions for Grade 8

📚 Quick Study Guide

• 🗺️ The distance formula calculates the distance between two points in a coordinate plane.
• 🔢 The formula is: $d = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2}$, where $(x_1, y_1)$ and $(x_2, y_2)$ are the coordinates of the two points.
• ➕ Make sure to square the differences in x and y coordinates *before* adding them!
• 📐 The distance is always a positive value.
• 💡 Remember to simplify the square root at the end if possible.
