14.2 Distance in a coordinate plane

Front

What is the distance formula?

Back

D = R * T (Distance = Rate * Time)

Front

How do you calculate the distance between two points on a coordinate plane?

Back

Use the distance formula: D = √((x2 - x1)² + (y2 - y1)²)

Front

If each grid unit represents 20 miles, how do you convert grid units to miles?

Back

Multiply the number of grid units by 20.

Front

What is the distance between the points (6, 4) and (6, -6)?

Back

10 blocks (vertical distance)

Front

What is the distance between the points (9, -3) and (9, 1)?

Back

4 units (vertical distance)

Front

What is the distance between the points (0, 5) and (0, 8)?

Back

3 units (vertical distance)

Front

If a car travels at 40 miles per hour, how long will it take to travel 120 miles?

Back

3 hours (Time = Distance/Rate)

Front

What does a negative distance indicate in a coordinate plane?

Back

It indicates a direction or position relative to a reference point, not an actual distance.

Front

How do you find the horizontal distance between two points with the same y-coordinate?

Back

Subtract the x-coordinates: |x2 - x1|.

Front

How do you find the vertical distance between two points with the same x-coordinate?

Back

Subtract the y-coordinates: |y2 - y1|.
