two points form a line. (x1,y1)(x2,y2)
no 2 points form a line, 3 points form a plane
one point can form a line! horizontally or vertically... but a line doesn't need any points.
Normally a straight line segment.
Any three points which do not form a line.
Points on an axis connected to form a line
No. Any two points can be made to form a line.
A plane is named by three points in the plane that is not on the same line.
a straight line
To prove that three points are colinear, pick two points and form the equation of the line they describe, and then see if the third point lies on that line.
only two points are required to form a line .One is the starting point and other is the end point
One line only. This is because by definition a line only needs two points. Three points not in a line would make a plane when connected. Two points, when connected, form a line in which there is only one way to pass through points a and b.
There are an infinity of points 4cm from a given line. These points form 2 lines parallel to and either side of the original line. Equally, there are an infinite number of points 4cm from a given point on the original line. These points lie on the circumference of a circle radius 4cm with its centre at the given point. There are only 2 points that fulfil both conditions. These points are found on the circumference of the circle where a diameter perpendicular to the original line and passing through the given point meets the circumference of the circle. These two points are also where the two parallel lines form tangents with the circle.
