Solve each system by graphing .
\n" ); document.write( "Y = -x + 1
\n" ); document.write( "Y= -4x - 2
\n" ); document.write( ":
\n" ); document.write( "If you wish to simplify by dividing by 2, you must divide y by 2 also, but in this case you would not do it. You want y to have a coefficient of 1
\n" ); document.write( "Just choose a least two values for x and find y for each equation. Plot these coordinates
\n" ); document.write( ":
\n" ); document.write( "Using x = 0 is easy, gives you the y intercept, let x = 2 and find y
\n" ); document.write( "y = -x + 1
\n" ); document.write( "y = 0 + 1
\n" ); document.write( "y = 1
\n" ); document.write( "x=2
\n" ); document.write( "y = -2 + 1
\n" ); document.write( "y = -1
\n" ); document.write( "Two pairs, 0,1; 2,-1
\n" ); document.write( "and
\n" ); document.write( "y = -4x - 2
\n" ); document.write( "y = -4(0) - 2
\n" ); document.write( "y = -2
\n" ); document.write( "x=2
\n" ); document.write( "y = -4(2) -2
\n" ); document.write( "y = -10
\n" ); document.write( "Two pairs, 0,-2; 2,-10
\n" ); document.write( "Should look like this
\n" ); document.write( "\"+graph%28+300%2C+200%2C+-6%2C+5%2C+-12%2C+10%2C-x%2B1%2C-4x-2%29+\"
\n" ); document.write( "they do intersect so there is one solution; -1,2 \n" ); document.write( "
\n" );
