**Explore and Grow**

Choose a location for your buried treasure on the grid. Choose a point where two grid lines My Treasure intersect. An example is shown.

Take turns with a partner guessing the location of each other’s buried treasure. Keep track of your guesses on the grid. After each guess, give a clue to help yourMy Guessespartner, such as “my treasure is northwest of your guess.”This is an image Continue to guess until a treasure is located.

**Reasoning**

The point where the horizontal number line and the vertical number line intersect is called the origin. Why do you think it is called that?

**Think and Grow: The Coordinate Plane**

**Key Idea**

A coordinate plane is formed by the intersection of a horizontal number line and a vertical number line. An ordered pair is a pair of numbers that is used to locate a point in a coordinate plane.

**Example**

Write the ordered pair that corresponds to point M.

The horizontal distance from the origin to point M is __ units. So, the x-coordinate is __.

The vertical distance from the origin to point M is ___ units. So, the y-coordinate is ___. The ordered pair is __.

**Think and Grow: Graph and Analyze Relationships**

**Example**

For each glass of iced tea Newton makes, he uses 2 spoonfuls of iced-tea mix and 10 fluid ounces of water. Newton uses 16 spoonfuls of iced-tea mix. How many fluid ounces of water does he use?

**Step 1:** Find the first several numbers in the numerical patterns for the amounts of iced-tea mix and water.

**Step 2:** Write the ordered pairs from the table.

**Step 3:** Plot the ordered pairs. Connect the points with line segments.

Because the ordered pairs follow a pattern, you can extend the line to the point where the x-coordinateis 16.

When the x-coordinate is 16, the y-coordinate is ___

So, Newton uses __ fluid ounces of water.

Answer:

(2, 10), (4, 20), (6, 30), (8, 40), (10, 50), (12, 60), (14, 70), (16, 80)

Because the ordered pairs follow a pattern, you can extend the line to the point where the x-coordinate is 16.

When the x-coordinate is 16, the y-coordinate is 80

So, Newton uses 80 fluid ounces of water.

**Show and Use**

Question 1.

Use the graph above. Newton uses 18 spoonfuls of iced-tea mix. How many fluid ounces of water does he use? Explain your reasoning

Answer: 100

When the x-coordinate is 18, the y-coordinate is 100

So, Newton uses 100 fluid ounces of water.

**Directions:**

- Each player arranges four Treasure Hunt Gold Bars on the My Treasure coordinate plane, horizontally or vertically.
- On your turn, name an ordered pair in the coordinate plane. If your partner says you found part of a gold bar, then plot the ordered pair in red. Otherwise, plot the ordered pair in black. Your turn is over.
- On your partner’s turn, if your partner finds part of a gold bar, then plot a red on the ordered X pair in the coordinate plane. Tell your partner when all parts of a gold bar have been found.
- The first player to find all parts of the partner’s gold bars wins!

Answer: \(\overline{A C}\) is longer than \(\overline{G E}\).

Find the distance between the points.

Question 18.

(0, 0) and (0, 4)

Answer:

The formula for distance between the points is √(x2 – x1)² + (y2 – y1)²

= √(0 – 0)² + (4 – 0)²

= √16

= 4

Thus the distance between the points is 4.

Question 19.

(3, 2) and (3, 9)

Answer:

The formula for distance between the points is √(x2 – x1)² + (y2 – y1)²

= √(3 – 3)² + (9 – 2)²

= √49

= 7

Thus the distance between the points is 7.

Question 20.

(0, 5) and (7, 5)

Answer:

The formula for distance between the points is √(x2 – x1)² + (y2 – y1)²

= √(7 – 0)² + (5 – 5)²

= √49

= 7

Thus the distance between the points is 7.
