### Cartesian Plane/Coordinate Grid

Before we continue with graphing, you may find it helpful to review how the Cartesian Plane (coordinate grid) works by trying the Whack-a-Mole game on the next page.

Here's a diagram of the coordinate grid.

The coordinates for point A are (3, 4) *(right 3, up 4) - Quadrant I*

The coordinates for point B are (2, -4) *(right 2, down 4) - Quadrant IV*

The coordinates for point C are (-3, -2)* (left 3, down 2) - Quadrant III*

The coordinates for point D are (-2, 2)* (left 2, up 2) - Quadrant II*

### Relationships from Graphs

Look at the ordered pairs and this graph and try to see the relationship between x and y.

(0,2), (1, 4), (2,6), (3,8)

The relationship can be described by comparing the value of x with the value of y.

You should be able to see that every time x increases by 1, y increases by 2.

Because x and y can take fractional values, join the points with a line.
