You can put this solution on YOUR website!
1) it will be the same as in the equation y=-3x+2. the gradient or slope is -3
\n" ); document.write( "2) y=-3x+b
\n" ); document.write( "plug in x and y to find b
\n" ); document.write( "-1=-3*2+b
\n" ); document.write( "-1=-6+b
\n" ); document.write( "add 6
\n" ); document.write( "5=b which is the y intercept
\n" ); document.write( "y=-3x+5\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "
