A (1, 3) and B (–1, 1).
i) AB cuts the -axis at the point C. Write down the coordinate of C.
ii) If the line joining (–1, k) and (3, 0) intersects AB at right angles,
find the value of k.
C(-2, 0), k=4
C( 2, 0), k=4
C(0,2), k=5
C(0,-2), k=5
The line segment joining A(2,3) and B(6, -5) is intersected by x – axis at a point K. Write down the ordinate of the point K. Hence, find the ratio in which K divides AB.
