Midpoint of the line joining the points (x1,y1) and (x2,y2) is (x1+x22,y1+y22).
True
False
True. Midpoint of the line joining the points (x1,y1) and (x2,y2) is (1(x1)+1(x2)1+1,1(y1)+1(y2)1+1) = (x1+x22,y1+y22).
The slope of a line joining the points (x1,y1) and (x2,y2) is y1−y2x1−x2.
The coordinates of the mid-point of the line segment joining two points P(X1, y1, z1) and Q(x2, y2, z2) are:
