Find the coordinates of the mid-point of the line joining the points (x_1, y_1) and (x_2, y_2).

If the coordinates of the mid-point of the line segment joining the points (2, 1) and (1, - 3) is (x, y), then the relation between x and y can be best described by

Derive the formula to find the co-ordinates of a point which divide the line joining the points A(x_1,y_1,z_1) and B(x_2,y_2,z_2) internally in the ratio m:n .

The coordinate of the mid-point of the line segment joining the points (4,5,3) & (-2,1,-1) is

The coordinates of the point which divides the line joining (x_(1),y_(1)) and (x_(2),y_(2))

The coordinates of the point which divides the line segment joining the points (x_1;y_1) and (x_2;y_2) internally in the ratio m:n are given by (x=(mx_2+nx_1)/(m+n);y=(my_2+ny_1)/(m+n))

IF the z-coordinates of a point C on the line - segment joining the points A(2 , 2 , 1) and B ( 5 , 1 , - 2) is -10 , then find the x - coordinate of C .

The coordinates of any point on the line-segment joining the points ( x _(1) ,y_(1) , z_(1)) and (x_(2), y_(2),z_(2)) are ((x_(1)+kx_(2))/(k + 1),(y _(1) + ky_(2))/(k + 1),(z_(1)+kz_(2))/(k + 1)) , then the value of k will be _
