Quadrant II Quadrant I Origin Quadrant III Quadrant IV x-axis All points on a graph are plotted by first
finding the x-coordinate and then the
y-coordinate
y-coordinate
You always graph a point starting from

the Origin
Origin
All points are written in the form ( x , y ) Quadrant II Quadrant I x is negative x is positive
y is positive y is positive Quadrant III Quadrant IV x is negative x is positive
y is negative y is negative Point (3,5) In order to graph a line, you need to
know either:
know A point and the
