Darren graphs the linear equations y=-2/5x+3 and 2x+5y=15. The graph look identical so he believes that the equations represent the same line. What mathematical argument can he construct to show that the two forms are equivalent?

Respuesta :

Darren can change the 2x+5y=15 into slope-intercept form and it would be the same equation therefore on a graph it would be the same line because the slope and y-intercepts are the same
