Determine graphically the co-ordinates of the vertices of the triangle formed by the equation whose sides are y = x; y = 2x; x+y = 6. ( Also area and co-ordinates )

Expert Answer:

To draw y = x, we will plot the points (1,1) and (0,0).
To draw y = 2x, we will plot the points (1,2) and (0,0).
To draw x + y = 6, we will plot the points (0,6) and (6,0).
