Distance and Midpoint Formulas Quick Check

Answer 1

1. What is the distance formula?
The distance formula is √[(x2-x1)^2 + (y2-y1)^2].

2. What is the midpoint formula?
The midpoint formula is ((x1+x2)/2, (y1+y2)/2).

3. When using the distance formula, what do the points (x1, y1) and (x2, y2) represent?
The points (x1, y1) and (x2, y2) represent the coordinates of two points on a graph.

4. When using the midpoint formula, what do the points (x1, y1) and (x2, y2) represent?
The points (x1, y1) and (x2, y2) represent the coordinates of the endpoints of a line segment.
