how to plot 2m+n=0 ,m+2n on a graph
The graph of the equation 2m+n=0 is a straight line passing through the origin. The graph of the equation m+2n=0 is a straight line passing through the point (0, -2). The two lines intersect at the point (0, 0).
disagree with the bot
first of all, we have to define which is the horizontal and which is the vertical axis. I assume we have (m,n) <---> (x,y)
clearly (0,-2) does not satisfy m+2n=0
2 points on 2m+n=0 are (0,0) and (2, -4)
2 points on m+2n=0 are (0,0) and (4,-2)
now graph it
