You can put this solution on YOUR website!
36) THE LINE FORMULA IS:
\n" ); document.write( "Y=mX+b WHERE (m)=SLOPE & (b)=Y INTERCEPT.
\n" ); document.write( "NOW SUBSTITUTE THE X & Y POINTS & SOLVE FOR THE Y INTERCEPT (b).
\n" ); document.write( "0=-3/4*-2+b
\n" ); document.write( "0=6/4+b
\n" ); document.write( "b=-6/4
\n" ); document.write( "b=-1.5 FOR THE Y INTERCEPT. THUS THE LINE EQUATION IS:
\n" ); document.write( "Y=-3X/4-1.5 OR Y=-.75X-1.5 ANSWER.
\n" ); document.write( "-----------------------------------------------------------------
\n" ); document.write( "38) 3X+5Y=15
\n" ); document.write( "5Y=-3X+15
\n" ); document.write( "Y=-3X/5+15/5
\n" ); document.write( "Y=-.6X+3
\n" ); document.write( "THUS A LINE PARALLEL TO THIS LINE & PASSING THROUGH (0,9) HAS A SLOPE OF -.6. NOW SUBSTITUTE THE X & Y POINTS (0,9) & SOLVE FOR THE Y INTERCEPT.
\n" ); document.write( "9=-.6*0+b
\n" ); document.write( "b=9 IS THE Y INTERCEPT.
\n" ); document.write( "THUS THE EQUATION FOR THIS LINE IS Y=-.6X+9
\n" ); document.write( "--------------------------------------------------------------
\n" ); document.write( "2 SOLUTIONS. NOW YOU FINISH THE HOMEWORK. :-)
