Algebra.Com's Answer #47914 by checkley71(8403) ![]() You can put this solution on YOUR website! SLOPE = (Y2-Y1)/(X2-X1) \n" ); document.write( "(3+3)/(-8-8) \n" ); document.write( "9/-16 \n" ); document.write( "-9/16 IS THE SLOPE. \n" ); document.write( "NOW SUBSTITUTE ONE SET OF (X,Y) POINTS AND SOLVE FOR THE Y INTERCEPT(b). THUS: \n" ); document.write( "-3=-9/16*8+b \n" ); document.write( "-3=-9/2+b \n" ); document.write( "b=-3+9/2 \n" ); document.write( "b=-3+4.5 \n" ); document.write( "b=1.5 THUS THE LINE EQUATION IS \n" ); document.write( "Y=-9/16X+1.5 \n" ); document.write( " |
