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?
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
