You can put this solution on YOUR website!
You can graph by taking both ordered pairs, graphing them on a Cartesian plane, and drawing a line through them (since the equation is linear). The domain and range of a linear equation are unrestricted, so to find another ordered pair, you can substitute any value into x (or y) and solve for the other variable. \n" ); document.write( "
