Understand the coordinate plane and plot points
The coordinate plane is a two-dimensional surface for graphing points and lines.
The coordinate plane has two axes:
The axes divide the plane into 4 quadrants:
| Quadrant | x | y | Example |
|---|---|---|---|
| I | + | + | |
| II | − | + | |
| III | − | − | |
| IV | + | − |
Points are written as :
: Right 3, Up 2 : Left 4, Up 1 : On y-axis, Down 5 : Right 2, On x-axis
