#### Presentation Transcript

How can we use absolute value to find the distance between points F (-8,-4) and G (3,-4)?

In this lesson you will learn to find the distance between two points that are in different quadrants by using a coordinate plane.

A (0,4)

6 units

B (6,4)

A

B

|0-6|= |-6| = 6

OR

|6 – 0|= |6| = 6

Begin by moving along the y-axis first, and then along the x-axis when finding an ordered pair.

(6,4)

Returning to the origin after plotting the x value, and then moving on the y-axis.

In this lesson you have learned to find the distance between two points that are in different quadrants by using a coordinate plane.

What is the distance between the two coordinate pairs

A (2,-3) and B (-6,-3)?

Use absolute value and the coordinate plane to solve the problem.

What is the distance between the two coordinate pairs

C (-5,4) and D (-5,-9)?

Use absolute value and the coordinate plane to solve the problem.

• Distance Challenge:

• 1. Create cards that have an ordered pair on each card. Be sure to use all four quadrants of the coordinate plane.

• 2. Draw to cards. Plot the points on the coordinate plane.

• 3. Find the distance between the two points.

• Dice Challenge:

• 1.You will need one or two dice for this challenge.

• 2.Before you roll, decide if the value will be positive or negative.

• 3. Roll the dice and record the number as the x value. Roll again, but this time record the number as the y-value. Repeat to create a second ordered pair.

• Plot the points and find the distance between them.

Which of the following coordinate pairs has a distance that is 12 units?
