Using the Rectangular Coordinate System

[Bite-Size Tutorial] Mastering the Rectangular Coordinate System

📌 What is Rectangular Coordinate System? ➜ In algebra, a grid system is used to show a relationship between two variables (like 𝑥 and 𝑦).

📌 What are Quadrants? ➜ The 𝑥-axisand𝑦-axis divide the rectangular coordinate system into four regions (I – IV).

📌 Every point in the system is represented by an Ordered Pair. ➜ The first number in the pair is the 𝑥-coordinate of the point, and the second number is the 𝑦-coordinate of the point.

📌 What is Origin? ➜ The point (0, 0), where the 𝑥-axis and 𝑦-axis intersect.

✏️ Substitute the 𝑥- and 𝑦-values of the ordered pair into the equation ➜ Is the equation a true statement ? ➜ If it is true, the number is a solution. If it is not true, the number is not a solution.
