Distance between two points and the midpoint
The distance formula is an algebraic expression used to determine the distance between two points with the coordinates \( (x_1, y_1)\) and \( (x_2, y_2)\).
Find the distance between (-1, 1) and (3, 4).
This problem is solved simply by plugging our x- and y-values into the distance formula:
Sometimes you need to find the point that is exactly between two other points. This middle point is called the "midpoint". By definition, a midpoint of a line segment is the point on that line segment that divides the segment in two congruent segments.
If the end points of a line segment is (x1, y1) and (x2, y2) then the midpoint of the line segment has the coordinates:
Find the midpoints between the coordinates (-4, -1) and (6,7)
