Expert Answer:

begin mathsize 11px style Let space space straight X space axis space divides space the space line space joining space left parenthesis 2 comma space minus 3 right parenthesis space and space left parenthesis 5 comma space 6 right parenthesis space in space the space ratio space straight r space colon space 1. straight Y space coordinate space of space the space point space on space straight X space axis space is space 0. Hence comma space using space section space formula space for space straight Y space coordinate space we space get 0 equals fraction numerator straight r cross times 6 plus 1 cross times negative 3 over denominator straight r plus 1 end fraction rightwards double arrow 6 straight r minus 3 equals 0 rightwards double arrow straight r equals 3 over 6 equals 1 half Hence comma space straight X space axis space divides space the space line space segment space joining space left parenthesis 2 comma space minus 3 right parenthesis space and space left parenthesis 5 comma space 6 right parenthesis space internally space in space the ratio space 1 colon 2 end style
