You need two points to determine a line. A single point can have an infinite number of lines passing through it.
In order to draw a straight line, two unique ordered pairs are needed. This is because two unique points determine a line and an ordered pair represents a point.
No because a defined straight line has 2 end points.
A straight line may be extended in either direction indefinitely. A ray is the part of the straight line beginning at a given point and extending limitlessly in one direction. A line segment is a part of the straight line between two of its points, including the two points.
Two points are sufficient to uniquely determine a straight line. It is generally best to select point that are as far apart as possible. It is also a good idea to pick one extra point somewhere between the two extremes. It does not need t be exactly in the middle. This point acts as a check. If the three points are not in a straight line then there is an error in one of the calculations so you need to check back. If the points are in a line you should be OK. It is, of course, possible, that you made two (or more) matching errors but, hopefully, that is not very likely.
line of best fit
Two distinct (different) points are needed to determine a line.
In coordinated geometry the points on a straight line will determine its equation.
In order to draw a straight line, two unique ordered pairs are needed. This is because two unique points determine a line and an ordered pair represents a point.
2 points
2 points determine a straight line and are always, by definition, collinear.
Two. Two points determine a line. Three points determine a plane.
A line contains an infinite number of points but it takes only two points to determine a line.
2 points. However, the farther apart the 2 points the striaghter the line will be, unless you move the straight edge!!.
alternatives to determine the equation straight line through two points?
A Straight Line is always the shortest distance between two points.
2 points determine a line.
A set of points on a straight line are called 'collinear points'.
