Distance and Reflection in Coordinate Geometry

The video tutorial covers the concept of calculating distance in coordinate planes using absolute values. It explains reflections across the x and y axes, demonstrating how to reflect points. The tutorial also includes practical applications of these concepts, such as calculating distances in real-world scenarios, and provides exercises for students to practice these skills.

What is the main objective when finding the distance between two points on a coordinate plane?

• To use the Pythagorean theorem

• To use absolute value

• To use linear equations

• To use trigonometric functions

When reflecting a point across the x-axis, which coordinate changes?

• Neither coordinate

• Both coordinates

• The y-coordinate

• The x-coordinate

If a point (7, 3) is reflected across the y-axis, what is the new point?

• (-7, 3)

• (7, -3)

• (-7, -3)

• (7, 3)

How do you calculate the distance between two points on the same side of an axis?

• Multiply the coordinates

• Subtract the absolute values of the coordinates

• Add the absolute values of the coordinates

• Divide the coordinates

What is the distance between the points (3, 2) and (3, 5) on the coordinate plane?

• 3

• 1

• 5

• 2

When points are on opposite sides of an axis, how is the distance calculated?

• By subtracting the absolute values of the coordinates

• By adding the absolute values of the coordinates

• By dividing the coordinates

• By multiplying the coordinates

What is the distance between the points (1, 3) and (1, -5) on the coordinate plane?

• 8

• 7

• 6

• 5

If each unit on a coordinate plane represents 10 miles, what is the distance in miles between two points 9 units apart?

• 60 miles

• 70 miles

• 80 miles

• 90 miles

How long will it take to travel 90 miles at a speed of 60 miles per hour?

• 2 hours

• 1.5 hours

• 1 hour

• 2.5 hours

If each unit on a coordinate plane represents 5 miles, how many miles are between two points 8 units apart?

• 35 miles

• 40 miles

• 30 miles

• 45 miles
