1.	If midpoint of the line segment joining the points p( 6,b-2 ) and (-2,4) is (2,-3) find the value
Answer» According to questionPR = RQ or R is mid-point of PQUsing mid-point formula x\xa0{tex}= \\frac { x _ { 1 } + x _ { 2 } } { 2 }{/tex}\xa0and y\xa0{tex}= \\frac { y _ { 1 } + y _ { 2 } } { 2 }{/tex}{tex}\\frac { b - 2 + 4 } { 2 }{/tex}\xa0= - 3{tex}\\Rightarrow{/tex}\xa0b + 2 = - 6\xa0{tex}\\Rightarrow{/tex}\xa0b = - 8
