Coordinate Plane

Coordinate Plane
• Y-Axis – The vertical line in the coordinate plane
• X-Axis – The horizontal line in the coordinate plane
• Coordinates – The x-values and the y-values• Origin – The point where the x-axis and the y-
axis meet.

Naming Points
You can use two numbers to name every point in the plane. These two numbers are called an ordered pair.
(x,y)
– Think alphabetically! We always write the x value first and then the y value

Plotting Points
• Think of the coordinate points as directions of how to get to the point from the origin.
• X-Value tells you how far to go left or right– Positive = Right– Negative = Left
• Y-Value tells you how far to go up or down– Positive = Up– Negative = Down

What if they are on an axis?
• Points on the x-axis– The y-value for points on the x-axis is 0
• Points on the y-axis– The x-value for points on the y-axis is 0
