The end points of a line segment are (2, 3), (4, 5). Find the slope of the line segment.

Some points are plotted on a plane such that any three of them are non collinear. Each point is joined with all remaining points by line segments. Find the number of points if the number of line segments are 10.

If A (m/2, 5) is the midpoint of the line segment joining Q(-6, 7) and R(-2, 3), then find the value of m.

The slope of a line is double of the slope of another line. If tangent of the angle between them is (1)/(3) , find the slopes of the lines.

The projection of a line segment on the axis 1, 2, 3 respectively. Then find the length of line segment.

The projection of a line segment on the axis is 2, 3, 6 respectively. Then find the length of line segment.

If the angle between two lines is (pi)/(4) and slope of one of the lines is (1)/(2) , find the slope of the other line.

The length of a line segment is 10 units . If the coordinates of its one end point are (2,-3) and the abscissa of the other end point is 10, then its ordinate is . . . . .

Find the coordinates of the points of trisection (i.e., points dividing in three equal parts) of the line segment joining the points A(2,-2) and B(-7,4).

P (a, b) is the mid-point of a line segment between axes. Show that equation of the line is (x)/(a) + (y)/(b) =2.
