Front

What does the midpoint represent in a coordinate plane?

Back

The midpoint represents the point that is exactly halfway between two given points.

Front

How do you calculate the x-coordinate of the midpoint?

Back

Add the x-coordinates of the two points and divide by 2.

Front

How do you calculate the y-coordinate of the midpoint?

Back

Add the y-coordinates of the two points and divide by 2.

Front

What is the significance of the distance formula in geometry?

Back

It calculates the straight-line distance between two points in a coordinate plane.

Front

If the coordinates of two points are (x1, y1) and (x2, y2), what is the first step in using the distance formula?

Back

Subtract the x-coordinates: (x2 - x1) and the y-coordinates: (y2 - y1).
