# 3-3 Notes

### 3-3 The Coordinate Plane

Standard (P5) I will be able to plot points in the coordinate plane

Fold and cut ordered pair and coordinate plane foldable, and staple to

x: The first coordinate in the ordered pair.

Gives the location of the point in the horizontal

(left to right) direction y: The second coordinate in the ordered pair.

Gives the location of the point in the vertical

(up and down) direction.

Remember: x comes before y in the alphabet and in the ordered pair

On Front: II

(-,+)

III

(-,-)

I

(+,+)

IV

(+,-)

### Inside Foldable

•The point where the axis cross is called the

__________and its coordinates are ( , )

Origin (0,0)

•Find the point on the x axis, label it A. Its coordinates are ( , )

(-4,0)

•y axis- Label it B. It’s at ( , )

(0,9)

•Quadrant I- Label it C. It’s at ( , )

(6,5)

•Quadrant II- Label it D. It’s at ( , )

(-3,3)

•Quadrant III- Label it E. It’s at ( , )

( -9, -2)

•Quadrant IV-Label it F. It’s at ( ,)

(2, -5)

Y-axis

X-axis

Plot G ( 2, 3)

Plot H (-5, -3)

How is A( 2, -5) different than B(-5 , 2)?

Name a point that would be on the x-axis

Name a point that would be on the y-axis
