You can put this solution on YOUR website!
line k is x+3y=6, now put k in standard form ( y = mx +b )
\n" ); document.write( "y = -x/3 +2
\n" ); document.write( "i) three points on line k, (0,2), (3, 1), (-3, 3) note you pick x value, then solve for y
\n" ); document.write( "ii) graph of y = -x/3 +2
\n" ); document.write( "\"+graph%28+300%2C+200%2C+-10%2C+10%2C+-10%2C+10%2C+-x%2F3+%2B2%29+\"
\n" ); document.write( "iii) slope (m) of k is -1/3
\n" ); document.write( "iv) is (-54, 20) on line k?
\n" ); document.write( "20 = -(-54)/3 +2
\n" ); document.write( "20 = 18 +2
\n" ); document.write( "20 = 20
\n" ); document.write( "yes, point (-54, 20) lies on line k
\n" ); document.write( "
\n" ); document.write( " \n" ); document.write( "
