3-4, The Coordinate Plane (SBAC Review)
A coordinate plane is a grid formed by the intersection of two number lines. You can use a coordinate plane to locate and name points.
The y-axis is a vertical number line.
The x-axis is a horizontal number line.
The point (0,0) is where the two axes intersect. It is called the origin.
The axes divide the plane into four quadrants.
An ordered pair (x,y) gives the coordinates of the location of a point.
The x-coordinate tells the number of horizontal units a point is from the origin.
The y-coordinate tells the number of vertical units a point is from the origin.
