You can put this solution on YOUR website!
Y=5X/2+6 HAS A SLOPE OF 5/2 (RED LINE)
\n" ); document.write( "SO A PARALLEL LINE ALSO HAS A SLOPE OF 5/2.
\n" ); document.write( "NOW SUBSTITUTE THE (2,1) VALKUES FOR (X,Y) IN THE STANDARD LINE FORMULA & SOLVE FOR THE Y INTERCEPT THUS:
\n" ); document.write( "1=5/2*2+b
\n" ); document.write( "1=5+b
\n" ); document.write( "b=1-5
\n" ); document.write( "b=-4 THE Y INTERCEPT.
\n" ); document.write( "THUS THE LINE EQUATION IS:
\n" ); document.write( "Y=5X/2-4 ANSWER. (GREEN LINE)
