P 8.1
P8.1 I can demonstrate an understanding of equations using graphs, and table of values.





Do not do page 2 or 4. Also, skip going to the links.
Please do the pages listed at the bottom of the assignment.
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.
