Algebra.Com's Answer #665707 by josgarithmetic(39618)![]() ![]() ![]() You can put this solution on YOUR website! Substitute for x in the other equation and solve for y...\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "Do you want to solve purely by graphing? Still you need a little bit of algebra. Pick one equation; Pick x=0 and solve for y. Pick y=0 and solve for x. Now you have axis intercepts. Now pick the other equation. Again pick x=0 and find y; and pick y=0 and find x; and now you have the axis intercept for the other line. Graph the lines! Can you read the intersection point on the graph?\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "You should find that your two equations are of parallel lines and they will NOT intersect. \n" ); document.write( " |
