Algebra.Com's Answer #194040 by richwmiller(17219)![]() ![]() You can put this solution on YOUR website! They intersect at x=0 y=-5 \n" ); document.write( "plug in y=0 in the first and get x=5 \n" ); document.write( "plug in y=0 in the second and x=-5 \n" ); document.write( "plug in x=0 and get y=-5 for both \n" ); document.write( "if x=1 7-7y=35 -7y=28 y=-4 \n" ); document.write( "if x=1 7+7y=-35 7y=-42 y=-6 \n" ); document.write( "plot those points and draw the lines and see that they cross at x=0 y=-5 \n" ); document.write( " \n" ); document.write( " |
