The line joining A (2.3) and B (6,-5) meets thex-axis at P. Write down the y-coordinate of P. Hencefind the ratio AP : PB. |

Answer» Answer: The y-coordinate of P is zero because point P lies in X-axis. Ratio of AP:AB=3:5. Step-by-step EXPLANATION: I just want to mention that I am assuming you wanted to write A(2,3) and not A(2.3) Explanation: Let AP and PB be m and n respectively. Now, we do not know the value of x so in ORDER to make the equation work, we USE the y coordinate while applying section mid point formula. Therefore, =>y=-5m+3n/m+n =>0=-5m+3n/m+n [m+n goes to the lhs and becomes zero] =>5m=3n =>m/n=3/5 =>m:n=3:5. |
