Algebra.Com's Answer #593903 by anand429(138)![]() ![]() You can put this solution on YOUR website! I hope you are familiar with slope-intercept form of line \n" ); document.write( "i.e y=mx+c \n" ); document.write( "so for Line 1, \n" ); document.write( "952=0+c (for 1st end point) \n" ); document.write( "=> c=952 \n" ); document.write( "and 0=m*1111+c )for 2nd end point) \n" ); document.write( "=> 0=1111*m + 952 \n" ); document.write( "=> m= -952/1111 \n" ); document.write( "so the eqn. of 1st line is y=(-952/1111)x+952 -(i) \n" ); document.write( "Similarly, eqn of 2nd line is \n" ); document.write( "y=(-1187/863)x + 1187 -(ii) \n" ); document.write( "Solving eqns. (i) and (ii) will give point of intersection. \n" ); document.write( " |
