The line segment joining A(-1 3) and B(G, 5) is divided in the ratio 1 :3 at P,thepoint where the line segment AB intersects y-axis. Calculate(7) the value of a.(ii) the coordinates of P |

Answer» If point p is at y axis so coordinate of p is (0,y).so by section formula,(0,y)=(a-3/4,5+5/3*3)(0,y)=(a-3/4,5+5/4)so,a-3/4=0so, a=3and y=5+5/4=5/2so coordinate of p=(0,5/2) |
