Two point forms of a line.

Discussion OF Test Paper -1,2,3,4|| Two point form OF line

Consider the points A (2,4) and B (3,-1) By two point form find the equation of the line AB. Hence find the x - intercept and y-intercept of the line AB.

The number of straight lines can be formed through any two points out of 10 points of which 7 are collinear

If A(4,3), B(-4,3) are two points on the line AB write two more points on this line.

The point of form (a, -a) always lies on the line

There are m points on a straight line AB & n points on the line AC none of them being the point A. Tri- angles are formed with these points as vertices, when A is excluded (ii) A is included. The ratio of number of triangles in the two cases is

There are ten points in a plane. Of these ten points, four points are in a straight line and with the exceptionof these four points, on three points are in the same straight line. Find i. the number of triangles formed, ii the number of straight lines formed iii the number of quadrilaterals formed, by joining these ten points.
