You can put this solution on YOUR website!
Rewrite each equation in slope & y-intercept form\r
\n" ); document.write( "\n" ); document.write( "y-x=1 Equation #1
\n" ); document.write( "y+x=3 Equation #2\r
\n" ); document.write( "\n" ); document.write( "Equation #1 in slope & y-intercept form\r
\n" ); document.write( "\n" ); document.write( "y=x+1\r
\n" ); document.write( "\n" ); document.write( "Equation #2 in slope & y-intercept form\r
\n" ); document.write( "\n" ); document.write( "y=-x+3\r
\n" ); document.write( "\n" ); document.write( "The graphs of the two lines are\r
\n" ); document.write( "\n" ); document.write( "From the graph it appears that the solution (point of intersection) is (1,2)\r
\n" ); document.write( "\n" ); document.write( "It is always a good idea to check your answer. Substitute the solution (1,2) into the equations to see if equality still is the case.\r
