FIND THE POINT ON THE X AXIS WHICH IS EQUIDISTANT FROM ( 2,-5) AND ( -2, 9 )
THIS PROBLEM WHEN SOLVED CONSIDERING THE TWO PINTS GIVEN GIVEN AS P AND Q AND THE MID POINT AS R , WE GET PR = QR AND WE GET RESULT AS R = ( -7, 0 )
WHY DOES THE SECTION FORMULA REDUCED TO EQUIDISTANT FORMULA ( X1 + X2 )/ 2 SINCE M1 = M2 DOES NOT GIVE SAME ANSWER .
SO IS THE EQUIDISTANT FORMULA NOT VALID TO BE USED WHEN THE INTERSECTION IN ON THE AXIS ( X AXIS OR Y AXIS ).
