Determine the distance between two points on a plane

12/14: M3: Lesson 10: HDW determine the distance between points that lie on the same horizontal or vertical line. 

CCLS 6.NS.6b, 6.NS.6c, 6.NS.

Are you ready to learn?

• Be sure to have your notebook & pencil ready to take notes

• In the next slide, you will watch a video that will instruct you on how to find the distance between 2 points on a coordinate plane.

Let's try some examples

Remember: If the points lie in the same quadrant, subtract the absolute values of the coordinates.

If the points lie in different quadrants, add the absolute values of the coordinates.

Multiple Choice

Choose the expression that represents the distance between the two points

Hint: If the line segment is vertical: Add the absolute values

• |2| + (-4)

• |2| - |-4|

• |2| + |-4|

Multiple Choice

Use absolute value to identify the distance

between the points H and P.

• 3 units

• 4 units

• -3 units

Multiple Choice

Find the length of a line segments with the following endpoints.

(2,9)

(5,9)

Hint: The points lie in the same quadrant, so we subtract the absolute values

• -3

• 3

• -7

• 7

Multiple Choice

What is the distance between points (3, -5) and (3, -8)? Is the line vertical or horizontal?

• 1 unit; horizontal

• 2 units; vertical

• 3 units; vertical

• 3 units; horizontal

Multiple Choice

Find the distance between the points.

(–6,–10), (–2,–10)

Hint: since the y points are the same, just find the distance between the 2 'x' points

• 8

• 4

• 6

• 10

Multiple Choice

What is the distance between points (-7, 8) and (2, 8)?

• 4 units

• 3 units

• 9 units
