Welcome Back

Multiple Choice

Review: What is the ordered pair that represents where the gym is located?

• (1,7)

• (8,1)

• (7,1)

• (1,8)

x-value: moves Left and Right

y- value: moves Up and Down

Multiple Choice

Review: What is the ordered pair that represents where the movies are located?

• (6,5)

• (5,6)

• (4,2)

Labelling

Remember the number line...

Label where positive and negative numbers are.

Drag labels to their correct position on the image

Negative Numbers

Positive Numbers

Labelling

Remember the vertical number line...

Label where positive and negative numbers are.

Drag labels to their correct position on the image

Positive Numbers

Negative Numbers

Now that we have two number lines...let's put them together.

One number line goes left and right.
That is the X-Axis

Another number line goes up and down.
That is the Y-axis

Together they make what is called a coordinate plane

Multiple Choice

Where can I find the origin on a coordinate plane?

• (1,0)

• (0,0)

• (0,1)

• (3,0)

A coordinate plane has labels to help us navigate in two dimensions.

The Origin is in the middle (0,0)

There are four Quadrants made by the x and y axis.
Quadrant I
Quadrant II
Quadrant III
Quadrant IV

​Points in the Coordinate Plane

​The points in each of the 4 quadrants are identified using and ordered pair consisting of an x-coordinate and y - coordinate (x,y).

​

Multiple Choice

In which quadrant is the following point?

(-3, 2)

• Quadrant I

• Quadrant II

• Quadrant III

• Quadrant IV

Multiple Choice

In which quadrant is the following point?

(4, -3)

• Quadrant I

• Quadrant II

• Quadrant III

• Quadrant IV

Multiple Choice

In which quadrant is the following point?

(-3, -3)

• Quadrant I

• Quadrant II

• Quadrant III

• Quadrant IV

Graphing ​Points in the Coordinate Plane

Graphing in all four quadrants is the same.

First move left or right from the
origin to find the x-coordinate.

Then move up or down to find the
y-coordinate.
