I don’t know if this is right but for Y=4x+7 your m would be 4/1 and where you begin would be 7 2x-5y=10: you would take 10 and divide it by the two numbers in front (10 divided by 2= 5) (10 divided by -5=-2) For 3x+4y=16 you would do the same you did for the last equation (16 divided by 3= 5.3) (16 divided by 4=4
