You can put this solution on YOUR website!
(x,y) = (-1,3)
\n" ); document.write( "(x₁, y₁) = (2,-0.5)\r
\n" ); document.write( "\n" ); document.write( "m = (y - y₁) / (x - x₁)
\n" ); document.write( ".
\n" ); document.write( "m = (3-(-0.5)) / (-1-2) = -3.5/3
\n" ); document.write( ".
\n" ); document.write( "y = -(3.5/3)*x + b
\n" ); document.write( ".
\n" ); document.write( "Use one of the points to find 'b'.
\n" ); document.write( ".
\n" ); document.write( "3 = -(3.5/3)*(-1) + b
\n" ); document.write( ".
\n" ); document.write( "3 = 3.5/3 + b
\n" ); document.write( ".
\n" ); document.write( "b = 3-3.5/3 = 9/3 - 3.5/3 = 5.5/3
