It is a line segment.
Displacement includes the distance between the starting and ending points and the direction in which you travel.
If you have 3 points on the same line or line segment, and there is one point on the right, one point on the left, and one point that is not on either end but is in the middle, then that is the point which is between other points.
a line segment is not a point but a series of points between two definite end points
since you know of one points and the halfway point between the other point. just multiply the halfway point by 2 and this is the total distance between the two points.
It is the midpoint
The midpoint
They must be collinear.
Twice the distance between a point and halfway to the other point.
is a point that is halfway between the end points of a line
0). Considering any TWO points, you can calculate the slope of the line between them like this: Slope = (difference between the y-values of the two points) divided by (difference between the x-values of the two points). Use this technique to examine your THREE points, like this: 1). Calculate the slope of the line between Point-2 and Point-1. 2). Calculate the slope of the line between Point-3 and Point-1. 3). If the two slopes are equal, then the three points all lie on the same line.
a line.
Do you mean "Between two other points? If yes, when it lies on a straight line between both points that are farther away and on the same line.
