**Warmup**

Name the coordinates of the points on the graph below.

**Activity #1**

**Introduction to Cartesian Coordinate System.**

- Click in the applet below.
- Follow through by clicking in the subsequent windows to understand the development of the cartesian coordinate system.

**Activity #2**

**Locating Points on the Coordinate Plane.**

The colored points on the coordinate plane are target points for you to locate. Follow the instructions below..

- Hit each point by entering its coordinates as an ordered pair in the Input Bar, like this:
**(1,3)**. The Input bar is at the bottom left.

(1.) What do you notice about the locations and ordered pairs of ** B**,

(2.) How are they different from those for point ** A**?

(3.) Plot a point at (-2, 5). Label it **E**. Plot another point at (3, -4.5). Label it **F**.

The coordinate plane is divided into four quadrants,** I, II, III**, and **IV**, as shown here below.

The following are points on the coordiante plane; **G **= (5, 2), **H** = (-1, -5), and** I** = (7, -4).

**Activity #3**

`Locate a Point on the Coordinate axes.`

- Press “New Problem” to start a new problem.
- Draw the blue dot to the indicated point.
- Once you think your point is in the correct spot, check your answer by pressing “Check Answer.” If it is incorrect, it will say
**Try Again**. - Try dragging the point to the correct spot. If it is correct, it will say
**Great Job!** - Then, you can try a new problem!
- Graph at least ten points before quitting this activity. Remember, in an ordered pair such as (-4, 7) the first number represents movement on the X axis and the second number represents movement on the Y axis. X first Y second. You got this!

**Challenge #1**

In the applet below is an image of an archery target on a coordinate plane . The scores for landing an arrow in the colored regions are:

- Yellow: 10 points
- Red: 8 points
- Blue: 6 points
- Green: 4 points
- White: 2 points

Name the coordinates for a possible landing point to score:

- 6 points
- 10 points
- 2 points
- No points
- 4 points
- 8 points

Type the coordinates for each point in a separate line, using parentheses. (Replace the question marks for the coordinates of each point.)

**Challenge #2**

See how quickly you can find five target coordinates by dragging the red point to its target location. As soon as you locate a point correctly, the next point to locate pops up immediately. It is a timed exercise. Try to beat your own record!

**Challenge #3**

(1.) Write the coordinates of each point.

(2.) Graph these points in the coordinate plane: (-2, 3), (2, 3), (-2, -3), (2, -3).
