Slide 1

Linear Equations can be graphed on a Cartesian Coordinate system

Slide 2

x-axis

y-axis

Cartesian Coordinate system

Slide 3

Quadrant I

Quadrant II

Quadrant III

Quadrant IV

x-axis

y-axis

Origin

Slide 4

All points on a graph are plotted by first finding the x-coordinate and then the y-coordinate

All points are written in the form ( x , y )

You always graph a point starting from the Origin

x is positive

y is negative

Slide 6

Point (3,5)

Slide 7

In order to graph a line, you need to know either:

A point and the Slope of the line

Two points on the line
