Exploring Distance on the Coordinate Plane

What indicates a line is horizontal on a coordinate plane?

• Both coordinates are negative.

• The x-coordinates are equal.

• The y-coordinates are equal.

• Both coordinates are positive.

How do you determine a line is vertical?

• The x-coordinates differ.

• The x-coordinates are equal.

• The y-coordinates are equal.

• The y-coordinates differ.

To find the distance between two points on a horizontal line, you should:

• Multiply the x-coordinates.

• Subtract the x-coordinates.

• Subtract the y-coordinates.

• Add the x-coordinates.

What is the correct way to calculate the distance between two points on a vertical line?

• Multiply the y-coordinates.

• Subtract the smaller y-coordinate from the larger one.

• Add the y-coordinates together.

• Subtract the larger y-coordinate from the smaller one.

What indicates a positive distance between two points?

• The points are on a horizontal line.

• The points are on a vertical line.

• Subtracting the smaller coordinate from the larger one.

• Adding the coordinates together.

Which operation is used when subtracting integers to find distance?

• Division

• Multiplication

• Adding the opposite

• Subtraction

If a point moves 3 units to the east, what happens to its coordinates?

• The y-coordinate decreases by 3.

• The x-coordinate increases by 3.

• The y-coordinate increases by 3.

• The x-coordinate decreases by 3.

Moving 3 units south affects which coordinate?

• Decreases the x-coordinate by 3.

• Increases the x-coordinate by 3.

• Decreases the y-coordinate by 3.

• Increases the y-coordinate by 3.

What is the result of moving 3 units to the west from the point (2,1)?

• (-1,1)

• (2,-2)

• (5,1)

• (2,4)

How do you calculate the new coordinates after moving north?

• Add to the x-coordinate.

• Subtract from the y-coordinate.

• Add to the y-coordinate.

• Subtract from the x-coordinate.
