You can put this solution on YOUR website!
m=4/5,(2-4)
\n" ); document.write( "I get to y+4=4/5(x-2)
\n" ); document.write( "good to here.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "rewrite as y+4-4= 4/5x-2-4
\n" ); document.write( "this statement is not right.
\n" ); document.write( "you took the (x-2) out of the parentheses which messed up your equation.
\n" ); document.write( "it should have stayed in the parentheses until you were ready to remove it using the distributive law of multiplication.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "it should have been:
\n" ); document.write( "y + 4 - 4 = (4/5)*(x-2) - 4
\n" ); document.write( "you then need to simplify by multiplying the factors out using the distributive law of multiplication to get:
\n" ); document.write( "y = (4/5)*x - (4/5)*2 - 4 which simplifies to:
\n" ); document.write( "y = (4/5)*x - (8/5) - 4
\n" ); document.write( "since 4 is equivalent to 20/5, your equation becomes:
\n" ); document.write( "y = (4/5)*x - (8/5) - (20/5)
\n" ); document.write( "you can now combine the fractions with the same denominator to get:
\n" ); document.write( "y = (4/5)*x - (28/5)
\n" ); document.write( "
\n" ); document.write( "
\n" );
