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.
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.
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.
line of best fit
Two distinct (different) points are needed to determine a line.
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.
In coordinated geometry the points on a straight line will determine its equation.
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'.
