How do you calculate the distance between the points R(7, -2) and Q(-3, 5)?

Back

Front

What is the correct way to express the distance between points A(3, 1) and B(-2, -1)?

Back

Front

What is the first step in using the distance formula?

Back

Identify the coordinates of the two points you are measuring the distance between.

Front

What does the term (x2 - x1) represent in the distance formula?

Back

It represents the horizontal distance between the two points.

Front

What does the term (y2 - y1) represent in the distance formula?

Back

It represents the vertical distance between the two points.

Front

If the coordinates of two points are the same, what is the distance between them?

Back

The distance is 0, since there is no separation between the points.

Front

What is the significance of squaring the differences in the distance formula?

Back

Squaring ensures that all distances are positive and emphasizes larger differences.

Front

How can you verify your distance calculation?

Back

You can check by substituting the coordinates back into the distance formula and ensuring the calculations are correct.
