You can put this solution on YOUR website!
you mean how do you tell if a point is a solution to a given or derived equation. Plug it in and see if it makes the equation a true statement. If it does it is a solution on the graph of that equation
\n" ); document.write( ":example y=2x-3.....point (1,-1)
\n" ); document.write( ":
\n" ); document.write( "plug that point in
\n" ); document.write( "-1=2(1)-3
\n" ); document.write( "-1=-1 therefore this point is on the graph of y=2x-3
\n" ); document.write( ":
