Coordinate plane/Distance

Front

What is the formula to calculate the distance between two points (x1, y1) and (x2, y2) on a coordinate plane?

Back

The distance formula is: d = √((x2 - x1)² + (y2 - y1)²).

Front

What is the distance between the points (0, 6) and (0, -4)?

Back

10 units.

Front

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

Back

9 units.

Front

What is the vertical number line on a coordinate plane called?

Back

y-axis.

Front

What is the horizontal number line on a coordinate plane called?

Back

x-axis.

Front

In which quadrant is the point (-1, -3) located?

Back

Quadrant III.

Front

What are the coordinates of point A if it is located at (2, 7)?

Back

(2, 7).

Front

How do you determine the distance between two points that lie on the same vertical line?

Back

Subtract the y-coordinates and take the absolute value.

Front

How do you determine the distance between two points that lie on the same horizontal line?

Back

Subtract the x-coordinates and take the absolute value.

Front

What is the significance of the origin in a coordinate plane?

Back

The origin is the point (0, 0) where the x-axis and y-axis intersect.
